1932 Flash Graphene - The Safe Way Anyone Can Do

[@WarblyWark]

Graphene is one of those mesmerizing things. Theoretically you could also dope graphene this way as well. You just need to submerse the kapton tape in less than a millimeters depth in deionized water and add drops of your phosphorus or boron source in the areas you need them.

Dang. Another good reason to get a laser. At this rate I'm going to need a considerably bigger workshop...

[@seabeepirate]

There are rather small lasers available. Some are considerably smaller than an average sized 3d printer. For cutting I suggest a CO2 laser which are the big ones but for engraving or making graphene I’d suggest a diode laser with an overkill power rating run at low power for longevity. I don’t have any hands on experience with diodes but the main complaint I would have I think is the diodes burning out or losing power pretty quickly if you run them at high power.

[@dm42]

Glad to see some additional references to graphene! It's one of the things that got me hooked on the channel. I've gone through all the old content I could find and can't seem to find 2 videos where you used a couple of different mills to separate graphite flakes into graphene. One was using a vertical ball mill made from a repurposed variable speed drill, marbles, graphite, glycerine, and urrea. The other was using some sort of high end spice mill which had stone rollers in it instead of blades to do the same thing - again - using glycerine and urrea as the sticky substance to exfoliate the graphite layers. I'm hoping they aren't lost forever. What I was most interested in was the ratio of urrea to glycerine. I think I recall the basic design features of the apparatus well enough. Any help or pointers from you (or someone else in the community!) would be greatly appreciated. Keep up the great work, I always look forward to your videos.

[@pmvcallan]

If I remember right with the flash method as well, to get even slightly reasonable yields you would also need to do it in a rarefied, preferably inert atmosphere. The laser flashing method seems better for large scale production, as you can literally run it down a processing line with several laser heads.

[@Tyler-wg5xh]

Once I have my laser I plan on testing this. I want to scrape the graphene off and use it as an additive to UV cured resins and print with it.

Late to the party here, but it occurred to me that another application for this would be making DIY flexible circuit boards from scribed Kapton tape. Likely ultra-cheap too, since you're only paying for a bit of tape and the power necessary to run the laser. Heck, multilayer circuit boards would be trivial since you could just tape the stuff to itself after it's been scribed. I'll have to see if there's a tool library nearby when I can get my hands on a laser cutter like this so I can try it out.

Most of it was residue is from the toner, but I never got a chance to test it’s electrical conductivity or resistance. Some of it Was Reflective Almost Like Foil And That Got Me Thinking I know it sounds crazy, but scanning paper like that, might actually be the best way to test graphene, or flash it. Basically scanning material with a thin layer of carbon. Am I close? You could also put it in a wax and essentially let it dry and bake all day. Like the scanner. The more you use it, the more it deposits, the more it protects. To a point I had to scrape it off after a while. My guess it does that on the microscopic level but you can’t see it. It’s only one percent. I know each car isn’t a sheet of paper, but the graphing is already in the wax. I used to scan mountains of paper every day , and after a year or so, I got that.

Will you be restocking Graphene (and ink) on your Working Ink webstore, or have you stopped with the store altogether, as I don't notice any products in stock lol

[@jasonhaymanonthedrawingboard]

Well isn’t this interesting. Does that mean you can laser print graphene? In something like a fdm process? If this is so? then full graphene prints are are available for 3D printing purposes. I once joked about using graphene in tattoos and reconnective medicine. Being able to fix nerve and spinal cord issues. Maybe even fix motor neurones? Is seen someone reference a exo skeleton using graphene? Don’t know how true that is. But if so you have mobility aids. ballistic protection. countless other uses. In not too much a leap to get layers of nanotubes using a laser. Still want to spell laser with a z. But that something else. Graphene is being eyed for the next gen of solar cells if it can produce spike structures? The it likely to be multispectral? Working in a broad range of wavelengths. So it might just work at night? Even off the cosmic background radiation….? With regard to solar cell. It can make then just Nm is thickness. So it could be possible to etch it into glass? Maybe as a primary coating? I don’t know how much that would cost? But if you can make it? You could end up with graphene reinforced glass? Which would be excellent space flight materials?

Did you see the Tech Ingredients video about this? It was really good, although, not sure I'd be trying his method myself at home though 😅

no mate - I find him a bit boring and i went to the Dr Tour seminar - so from the horses mouth so to speak rather than a second hand version - I am actually a carbon chemist you know lol

@@ThinkingandTinkering If you aren't a researcher it's hard to know where to find good information, what works and what doesn't, what is nonsense... you and other channels are important because of it.

@@ThinkingandTinkering oh...didn't know that...and yes, I do find he can be somewhat dower in his presentation.

Overload..😅

Where is Rob and what have you done with him?! They have Rob under house arrest? He made a bunch of videos to sneak off on Vacation? Are you an AI generated Rob? Why is the store out of graphene ink? Channel got bought out by a large Corporation?! WHAT has been going on HERE?

[@ThinkingandTinkering]

lolol - i come up clean once i have a bath mate lolol

[@undernetjack]

@@ThinkingandTinkering Bath Time, then! Where's the ink? Tell me. Don't make me fly over there...(nah, I won't fly....but a boat maybe,)

'Graphene' is - graphite. That's it. Everything else is just blah blah.
