If you want to dissolve graphite , There is another green product that you can use with sonication , its called gum arabic

I am awed by how simple you make everything. Oh. Welcome home. Thank you for all your help.

You obviously live by the saying "Failure is but one step closer to success." My favorite.

Wow thanks for the info. I didnt know that here was so much kind of bonds. If you were a teacher, i would pay a million dollars for a simple course on chemistry. You are a genius and i love the way you teach.

I tried making the g-AlCl3 compound using my home-brew ferric chloride solution. I didn't have success in obtaining the dry crystals to make a powder, so I substituted for 10ml solution mixed in with the graphite and AlCl3 powder. It turned into a clump in the pipe. After cooking for 8hrs, there was some gas pressure. When I opened it, it smelled like propane gas. I tested the compound by comparison to your microwave exfoliation video. There was little to no arcing in 2 min of 1100w!

This one's great Robert like a proper lesson I learned something 👍

Absolutely fascinating Rob! You put this across so even a non-chemist guy like me can get a handle on it. Thanks!

best chemistry class on youtube :) i would love to see you work on copper oxide memristors and diy electroluminescent solutions

Very good explanation, thank you.

Nice work mate!

You would make it the same way but fill a wide flat container with water and pour the solution onto the water. Because it is ethyl acetate and graphene it will float and spread out and automatically form a graphene sheet

Depends what's in it. But there is often a lot of additives. You could try it and see

Good idea will do thanks

cheers mate - it really is easy

I heated the HCl solution to about 250F on a hot plate with the steel wool inside. Not having a round bottom flask to re-condense the vapors, I used celophane and kind of dished it into the jar. Seemed to work fine. It took several hours to dissolve. Next, I poured in 200ml of 3% peroxide, according to the nurdrage video. I turned up the heat to max close to 500F, left it for hours, and I saw very small crystals circulating. I poured the solution into a large evaporating dish on 500F

The high heat evaporated the solution down to a crusty red powder. This worked well to produce my AlCl3 powder, so I assumed it would work here, until I saw that you strain out the crystals from solution. I started over. Using the same procedure, when all my peroxide was mixed in, I made a dessicator bag with some NaOH powder in a cup. I left the solution in the bag 3 days with no results. So using the oven autoclave method, I tried making the g-AlCl3.

i am going to set up a page for this and i will put the link in the description - should be in the next couple of days - thanks mate.

Always great learning videos :) So I gather that non water based solvents are the route forward for the Wander Waal sheet bonds ? Is there any chance that paint stripper could be used ? lol, am staring at a 1 gallon container of it on the floor. Would guess it's too thick anyway.

that's a ot of questions and I shall try to deal with em one by one. You are right about NMP and it is an ultrasonic water bath cleaner of 50 watts. Sorry about the sound can't get everything right. But the important information is there

Robert: the most popular chemist on KZread :P I need to give this a try.

Hiya mate, I am not likely to redo this. It works in the same way any solvent does. A solvent forms a partial bond with the solute until there are sufficient partial bonds to overcome the molecular forces holding the solute rigid. You need a balance so that the solvents isn't too strong as it will also overcome the intermolecular bonds.

I'm going to try it!

Cheers mate

Lol you should see all the failures. It takes a while to get something to work but thanks for the comment

It would be interesting to see if different sonic frequencies would produce other effects, even chemical synthesis, using the carbon lattice.

Hi Robert, Ive been following your work for quite some time now and I think you are a genius. Just saw your latest video and heard you say that you had shown us how to make exfoliated graphite. Can you tell me in which video exactly did you explain that. Would appreciate it a lot if you could post the link to that video too.

I suppose so. My main interest is in energy technology so I have not really looked into it. But, I believe that being a gas barrier is on of the properties. I would guess you would need to look at cvd growth.

That was quiet interesting, an informative. One of the nice things of having a mental illness, I'm Bipolar II. Is that lately I have become a sponge, comprehending anything I see, hear, or read. The one luxury I don't have is, I have to keep a strong hold on reality. In other words when I daydream, it's a lot more difficult from me to come back from my trip! lol

Too much to do and not enough time to do it. I will bear in mind what you said and if I can fit it in I will

You could try a paint stripper but there will be a lot of additives and that will mean a high temp annealing process to get a useable film

Hi Robert, Have you considered the new method of making graphene using dry ice (solid carbon dioxide) and magnesium? Please let me know what you think about this method.

No probs mate

Thanks for sharing

I wil set up a PayPal later today and let you have the details. I like the ink jet idea but I will have to find a way of controlling particle size for that. I think it has to be less than 45 microns to go through the nozzle.

Huge fan! I've apparently spent my life convincing myself that I can't learn stuff like this, but you're getting through my thick skull. Question about bonds: Some of the HHO folks claim that the h2o bond can be split with less energy - less energy than is available from burning the resulting Brown's gas - by finding the right freq of high voltage , essentially over-unity. A buddy of mine claims that all the HHO generators are perpetual motion scams. Who's right?

Cheers mate, Chances are it's a little of both! - Myself i prefer to steer clear of such controversy as it takes up a lot of time and most of it is wasted - arguing about the pros and cons - everybody has an opinion. So, as far as brown's gas goes - i have no real opinion as I haven't worked with it. But, if i was going to look at that area I would probably look at electrolysis of urea. I know this doesn't really answer your question directly but it is the best answer i can give

I want a powdered form of graphene... should i evaporate the solution? Plz reply any one

Hmmm not sure what to suggest. Though that does seem like a lot of peroxide. What is your procedure?

Thanks for getting the book mate. Not quite sure what you mean here

I’m just thinking even if someone had a recycling/garbage center that also doubled as a “flash graphene foundry” of sorts, they could still use the other methods for making graphene and the processes could help make other operations more efficient. Just having Most (or all) different operations in a specific or given areas like a chemical plant, but for graphene

hello sir I just watch your video and really enjoy your explanation But I got something to ask What happens if make the sonification time longer than 3 hours? Are we gonna get much graphene? Thank you

The main problem is the ball mill it has to be a high energy type. The little thing people use for polishing pebbles won't do it - I know because I tried it and it failed. Still, maybe I did something wrong. Give it a go and let me know how it goes

I watched it all the way through on my iPad - no problems with it. I am afraid it must be a problem your end. Try downloading or watching later

I'm pretty sure he is using an intercalation compound. Probably carboxylic acid intercalated. Not sure on the liquid he pours on but could well be hydrogen peroxide or maybe a perchlorate. Either way I don't get too taken up with him.

I think I've mentioned before I come from the life science industry pharmaceutical research etc etc etc ad nausea we used simple Sonic caters differently we had stainlessSonic caters with holes in the bottom and tubing to drain them out the back. We never used containers we put the actual material directly in the sonicator and it works thousands of times better because you get more of the action directly on the material I just wondering if it wouldn't be worth trying that if nothing else it would increase efficiency TimeWise I was wondering have you ever tried that

I just had a though, what if you make this solution in a very wide and flat container? Would the graphene be mor easy to get off the solution?

There is no need to heat the steel wool will react as soon as it is dropped in the acid. Assuming you use a strong acid. 35% is sold in the UK as spirit of salts and in the US as pool cleaner. Really mistakes compound as you go along. So, you have to do your best with the starting materials. I suggest you try remaking you ferric chloride

Maybe you could do one. I get a bit sick of people asking me to make a capacitor. They are stupidly easy things to make. Make one yourself. There's lots of info on how to. It might be you are missing the point. Graphene is used for far more than supercapacitors - don't ask me what - google it. people want to know how to make it so they can research their own projects using it.

Starting from blender reduced graphite is there a household solvent suitable? I have the same sonicator but the starting point is too far ahead, hummers and expanded/microwaved graphite isn't possible here.

I bought what was supposed to be "expanded graphite" off of Ebay. I've seen videos where someone put some of this with a little bit of water in an ultrasonic cleaner and it looks like it's dissolving into a brownish/amber colored solution. In a glass it's a nice transparent caramel color. When I tried it, it seems to take MUCH longer and mine is dark gray/black with a kind of pearl shimmer to it. And a silvery, almost chrome like layer floats on the surface. I don't know if the shimmering stuff in suspension is the graphene or if the chrome-like film on top is the graphene. Or is it just suspended graphite? My 1st attempt seems very stable, has been in perfect suspension for days.....whatever it is. Also, if I put a couple drops of Dawn dish soap in while sonicating, the silvery layer breaks up and disappears. I'm wanting to use graphene to enhance a water based automotive paint sealant I'm working on. Anyone have any thoughts on what I have here? Thank you for any help you can give.

It must be the desired compound. Keep in mind that water graphene mix is like trying to dissolve Polycyclic Aromatic Hydrocarbons rings into water...solubility is low but does exist...this means the partition coefficient of graphene/octanol vs graphene/distilled water is very high order of magnitude so the affinity of the hydrophobic but slightly polarisable graphene layers for each other is much higher than for water...and they tend to stack on each other quite fast (pi-stacking) but the planes have very large surface vs water molecules that are probably often trapped between parallel reformed stacked planes. Monolayer or fine graphene stacked layer are essentially transparent and adsorb light into the UV for the polyaromatic plane but fluoresce all over the spectrum (as a function of the molecular surface) and for the pi-stacking part must be all over the light spectrum (reason why graphite is black). The restacking formation may account for pearlescence/silky shine of layer and if too much restack (like upon interface between liquid and air (hydrophobic) takes a metallic lustre. The stacking/restacking happens faster if solution is too concentrated... Water-graphene goes thus very fast to oversaturation. One idea would be to work with benzene, hexamethyl benzene or PAHC like naphatene, phenanthrene, anthracene, phenantrene... Those would be excellent solvents because of their molecular patenthood with the graphene planes... but those are sometimes expensive and carcinogenics... So maybe better to stick with other common organic solvents of medium volatility. Too high a volatility will generate troubles with regard to sonication due to adiabatic cavitation compression bubbles...heat and cracking or breaking of the graphene layers into tinier pieces.

Do you have to clean any residue from the acetone?

Sir ...i got this project on graphene synthesis... And i really want something new to do which no one has done yet plz help me... Or suggest anything

Hi Robert, can you please show us and draw again on your whiteboard, how an NMP solvent works in conjunction with these carbon based atoms and hexagonal molecules ? Many thanks. Regards, Stefan.

Hi Robert, I'm one of your fans, I've just bought your 101 graphene. I still learn how to make graphene. Do you have step by step instruction how to get graphene from dissolving graphite? Please let me know if you have it.

Could it be used as a means to plug leaks in a device meant to hold helium?

Great video explaining the different bonds! Having a snag with the compounds I made! None of them will exfoliate in the microwave. Thinking my home-brew reagents either too weak, or not at all what I thought they were! My ferric chloride doesn't boil off to make crystals, instead it turns into a red iron oxide powder. I have made it twice with 100ml HCl 37%, 100ml distilled water, 20g steel wool, disolve and stir in 200ml hydrogen peroxide 3%.

what about making graphene thru.electrolysis of a graphite electrode?Also could it be deposited on a substrate such as aluminium an atom thick to make a supercapacitor?

@ThinkingandTinkering

see later videos mate

I would be interested buying some. I would like to build some home made supercapacitors as some other devices. What would be very interesting is use it in an ink jet printer. I'm not sure how that would work. I seen some cool stuff printed with 3D printers, but that's a bit far off.

Maybe can you try to show us a small supercapacitor made from this material and then show us the capacity is has got ? This way we would be sure, that we can make really good capacitors and that would also help your sales of the raw materials... As one can already buy around 400 Farad caps for around 8 Euros over here, I wonder, if I really should try to make them myself... Well, if you could show also some kind of selfmade solarcell with this stuff, that would be really fantastic.....!

I'll have to test this method of cleaning catalysts of deposited graphite. The idea is to use CO, heat it, then let it cool in the presence of a nickel, or iron catalyst. This is a "Boudouard reaction" which is used to convert CO into CO2, but deposits graphite or graphene on the catalyst depending on the material it's made of. Since that has ethanol in it, I'll try that as a solvent first. Or course, I need to get a system where I can convert dry ice into CO with electrolysis (or UVs like someone, I think a Chinese company, did) first. The idea is to create tech for colonizing Mars. Ethanol is easy to make with a still using crop waste, and can just be evaporated when I need to reclaim it, so that would be easy to come by in situ.
