NightHawkInLight did a good video on that method, but it's a bit dangerous since you have to use a large capacitor bank. Also not cheap since you have to buy a boat load of the super caps and then also a quartz chamber. Out of all the methods besides CVD, which is out of the capabilities of many (most?) of us, probably the electro chemical is easiest, quickest, and produces decent enough graphene for electrical, thermal, and mechanical strengths applications (i.e. composites, cements, etc). I'm not sure, but I think that Rob leans to a combo of the electro-chemical, as well as the heat conversion of hemp to carbon and/or graphite, personally. At least, I got that impression from watching a boat load of his videos awhile back. Something I'm focused on is making cellulose nanocrystals and then converting that into carbon and graphite. I think the size and the inherent crystalline structure may provide a benefit. I'm not sure, but I think that is what is in the hemp that gives it such good properties, though it is also chemically exfoliated while heating (via potassium hydroxide).

@@justinw1765 I was thinking that Rob might have watched a few CHEECH and CHONG movies myself. Maybe he"s got one of those quartz pipes to flash off a little carbon press. I see much cleanup potential in Flash Joule processing, no fire, no chemicals. We can dig up our land fills and make them non toxic profitably.That's a win, win.

I think nanotubes would suit the endgame. I also think an interdigitated compartment wasn't considered for the flash method. I'm guessing the monoatomic layer between carbon electrodes is key. This is cutting edge stuff you are working on and you have lead.

Best ball mill I have seen Rob, and you will laugh it was a cement mixer. The mixer had all its blade cut out, and had big balls.

I wounder if you could use graphene on a thin plastic sheet to create an electtrostatic speaker?

I was about to ask if you could burn away layers of carbon until you had graphene. But then I realized that’s literally the first way I ever learned about making graphene. In an optical disc burner.

"Hematene"? Do you mean the carbon and/or graphitic converted hemp fibers? I would like to see Rob experiment with making cellulose nanocrystals, converting that into a graphite and testing it.

I no longer have my sonicator. I wasn’t too impressed with the results using water but I wonder if I replaced the water with glycerine if it would work better.

Hi Robert, did you do one on the Electro as the 3rd option ? Thanks Peter

Inspired by you, I've parsed some papers about graphene, and seen a few describing the interculculation of hydrogen atoms into the carbon lattice structure of the graphene honeycomb allotrope. In one of your previous videos, you were conducting experiments with magnetism and hydrogen generation. To make continuous graphene sheets, could we somehow take a sheared pile of honeycomb graphene with the hydrogen atom "locked" into it's center and utilize a sufficiently smooth magnetic plane to "pull" it all into place?

Dear Robert. I have a question. I created a silvery material from black graphite. I feel it's large graohene flakes/nanoplatelates but I told my friend and he said graphene is black. I said I think it's more silvery--especially when wetted. All the best electrical conductors are shiny and reflective. It seems graphene can be black, or if thin enough, totally clear. My question is what is this silvery stuff? (It's in your paint, too, that I got). Also, do you still feel 75% acetone and 25% water is a good mix or have you found a better solution?

I have always wondered how you know at what point you are done? What tells you that the powder now is graphene and you don't need to blend/mill/... it for another 4 hours? Is their a way to differentiate between graphene and ordinary graphite powder?

@justinw1765

There are a couple ways. Really, really, really good microscope. You can also test the electrical conductivity of the material. If you know the base line for the regular graphite source you're using, and then you get a significant increase over that in the possible graphene, or more likely, a more graphenic graphite in the electical conductivity, then you know you're doing something right.

Could I win a prize for directly converting cellophane or plastic sheet to graphene? Seems like getting a thin sheet by rubbing graphite on a thin sheet is adding ingredients and complexity. Cellulose, paper, thin polyethylene all contain a lot of linked carbon already. Plop it on some stainless steel and heat to 700C.

@justinw1765

It's a little more complex, but there is something to the general notion. After all, the hemp fibers when converted to carbon and/or graphite via heat and/or pressurization shows very high electrical conductivity and more over, because of its innate structure and that it also gets chemically exfoliated by potassium hydroxide during the process, the surface area is immense (helps to increase potential loading of ions), then yes, in a very general sense, there is something to that. What might be interesting in particular, is an instant, high heating and quick cooling of highly oriented, ultra high molecular weight polyethylene--the stuff they use to make ridiculously high tensile strength cord, rope, fibers, etc (A bike company is now using it in place of steel spokes for wheels). (Some trade names include Dyneema and Spectra, but there is plenty of Chinese brand versions). Why, the highly crystalline nature and in a continuous, connected structure, might provide an ideal pathway for electrons, making it very highly, highly conductive? Actually, that would be a good material to try in the flash-electro-heat version. The problem with this material is that it melts at a pretty low temp. Once it starts to get to that near melting temp, it also starts to lose it's high crystallinity which is what gives it its high tensile strength and high thermal conducitivity (Dynamic fabrics are as thermally conductive as some metals). You would have to super heat and cool it very quickly (which the flash method does) and in a completely inert atmosphere. All these methods of converting matter to carbon and graphite require an inert atmosphere (very low to no oxygen) btw. Otherwise, the materials burn up. (As far as I know, there are no thin, flat sheets of highly oriented UHMWPE made, though you can get sheets of regular UHMWPE).

Sounds interesting. How would one go about finding this out, and won't it vary some depending on size, shape, etc? And wouldn't the ultra sonic do, indirectly, what you're proposing would do more directly? Benefit might be less power/energy used, and/or more controlled shearing?

Instead of getting fancy, couldn't you just run the ball mill a bit slower so that the balls don't actually drop? I don't know, but perhaps if your container was nice and round inside, you could cast something by putting it in the container when it was on its side, assuming that the stuff you're using doesn't stick to the container.. Just a fraction of the volume. The result would fit closely to the inside of the container and, assuming that glycerin and/or the container are slippery enough, it would slide along, with the graphite caught between the object and the container. I guess you'd want to round the edges of the object so that more graphite was pushed under. I suspect this is so obvious that many people have already thought of it. If so, and it's well known, I apologize for tedious repetition.

..... electro chemical method?

Look at the graphene structure, 6 points, 6 lines, and many of these sixes. That's the mark of the beast 666. Also what can cause pain (Revelation 16:10) and “a noisome and grievous sore” (Revelation 16:2)? Only something medicinal can cause these. Not a chip implant. Also human body is 18% carbon. So therefore "a man's number" is also 666.
