The reason that Aluminum sheets are shiny on one side, and matte on the other, is that the final rolling of the sheets is so thin, that they lay it double to be able to roll it flat enough. The matte side is the side touching aluminum, and the shiny side is the one that was touching the roller.

yea, kitchen alu foil is NOT coated with plastic!

Attach the sheet to a speaker, hang over a container that is tall enough to stand the whole sheet up in, then play a low frequency sine wave through it so it's essentially being 'jiggles' up and down that way the bubbles get shaken off the sheet letting the acid get at new aluminium. I believe that you can use the same procedure to make electro-plating more efficient. Just a thought, awesome vids, new sub here 👍

Hi Robert, thank you for your contributions to the Global Community and KZread. Your videos and the great discussions that follow with many intelligent subscribers is amazing. I was thinking that a silk screen kit for making t-shirts and such would be excellent for laying on the liquids in even thin layers. These can be found at your local art supply shops, even toy stores for very little money. A little vibration after spreading the liquids may also help to even out distribution, maybe you could use your cell phone.

Thank you for posting these experiments. I totally understand that experimentation does not always result in "Success" as most understand "Success". Any true inventor knows that failure to produce the desired result may be a complete SUCCESS in terms of lessons learned, old theories proven wrong, surprising side effects, and the simple encouragement to improve on the obvious shortcomings of the current experiment which results in future learning and more refined experiments that one day may lead EVERYONE in a different direction than that which is currently considered "The way".

Hey, To get that thick layer of coating, approximately how much ( in mL) of graphene oxide did you use? I have very limited GO to work with so knowing this would really help me. PS. Great work! :)

Brilliant!!!!!

Does the strength of the graphene stay the same or is that sheet of graphene able to rip, tear or poke easily?

Caustic soda will also eat aluminium but may effect the varnish if too strong.

How about pulverising (spraying) the grepheene oxide on the aluminum sheet, would be applied in a thinner layer? Maybe this would give better results

Wonderful explanation. I had a little trouble with the heavy accent but the illustration and explanation was a good exercise. Discussing the thickness control; is the cross section of thick graphene the same as the single molecule layer, or does the plate become opaque and effectively a solid plate?

Note a correction: aluminum foil does Not have a coating of plastic. One side is shiny because it is double face rolled to thickness, then split to rolls for sale. The retardation of chemical reduction is due to the surface oxide of aluminum which is an inhibitor of further reaction until broken down. If you doubt this check out Alcoa manufacturing videos.

I live on a sailboat with a constant minimum of 2 nt current flowing with the tide. Basically im layering the sheets with only a hold at one end and lose on the other. Im going to cheat a bit and use a concentration of copper chloride in ionized water. that will be pumped by a small pump (a venturi would be best so that as i sail the atmospheric difference would create a vacume to move the solution over the graphene sheets. ) Im thinking in the ball park of 1000 sheets that are 8" inchs by 60". Should be interesting at least lol. It sure would be easier to buy some ink from you but im not opposed to making grahpene with electrolysis. I plan to build this as large as i need to power the boat through the water by electric motor when no wind is available so my solar panels will pump the solution in the sunlight and also charge a battery bank that is dedicated to providing the power to pump the solution when night falls. It will be assisted further by the graphite and magnesium generator that will be hanging over the back of the boat like a rudder. Perhaps ill just build that part directly onto the rudder.. who knows. Point is that im am determined to power my boat, heater, and cooking by the world around me and your clever tricks lol.

If the dispersion of the graphene is irregular, how well would this work for use as a Faraday cage to shield from microwave (imaging)? I was looking for an alternative to the cost of Y-shield paint or graphene sheets. I think it would be more effective if combined with either copper or silver particulate mixed in varnish, applied afterwards. Although it might be best to forego the reduction of the aluminum; it just isn't aesthetically pleasing.

Hiya Mate, Thanks for the kind comments - what you want is a varnish that allows the wood to breath - this is how they describe it and this type is the microporous stuff

If you add hydrogen peroxide to the hydrochloric acid, it should speed up the reaction quit a bit. When etching circuit boards, you generally use 2 parts hydrogen peroxide to 1 part hydrochloric acid. It takes about 5 mins to eat all the exposed copper. You could try using 5cm copper tape. You can buy 1 meter of 5 cm copper tape off ebay for about $2 or so. What if you where to coat something hard and smooth like a marble tile with the carbon solution, then after it dries, lift it with very sticky tape, then you would have the layer of carbon with a plastic backing, then you could expose it to laser light. No need for the acid bath.

What about airbrushing the graphene solution on? Surely this would give a thinner more uniform layer?

Does this product, made this way, have a higher thermal conductivity than copper?

instead of floor varnish, you should try a spray adhesive and a very fine mil plastic sheeting, ie dry cleaner bags is the perfect thickness.

Wish I could, but that's not possible right now. When I do make some, I would like to get the most conductive graphene possible, has to be better than silver or its not worth it because I will just use silver then, Do you recommend a process that will make a good conducting graphene, or are all the ways I have to make it the same?

what would happen if you attempted to produce the graphene and then desolve both the aluminium and the varnish?

There are lots of approaches you could take - one might be to use no binder and calender it - the sheet is made of individual plates it's not one whole sheet so there are going o be defects att he edges which will be weak points - you have to have some strategy to overcome that - so another might be CNTs added in.

Are these contiguous sheets the same as the sort you got with the pipe fitting pressure cooker assembly of yours and the kind you get via copper sheets + vapor deposition, IE an A4 sized single molecule with a mollecular weight beyond comprehension, or would it be more akin to dispersing a lump of graphite(lots of micro-sheets) into a sheet?
