OK I was pondering better ways to break down the graphite .
My best solution is to use a metal plate and a hammer .
My thinking is the graphite is usually broken down via blenders and such that the blades are striking the graphite to break it to make graphine .
Well a good old fashioned hammer should make small batches easy .

Granted if I get metal in the graphite it would taint the results but I'm not thinking of force to drive a railroad spike is nessesarry .
Just light taps and add more graphite then scrape the area to collect the graphene .

Oh yeah ,
I followed some videos and a fellow was claiming amazing results via adding graphene to the electrolyte . Deffinatly worth looking into .
I would have posted the video but this stinking thing wouldn't let me and now I can't find it again .
If y'all have thoughts please share

Hi K

The use of acetone will work with a blender or a malt mixer also a ring cleaner with that mix will also work and that is called sonication. That will be the process that I will use if I don't just buy it, its a tossup. I bought 10G for $35.00 and if I want 20G its $60.00 don't know if I can make it for that. LOL

Hi Kudzu

I don't know if i have understood your posting correctly where you want to crush Graphite to form Graphene.
You will still require the mixing stage as Doug as pointed out in his reply.

Please be careful when using Acetone it has a very low flash point.

I have been contemplating using naphthalene (mothballs are some times made of very high purity of this stuff) as it is basically two graphene rings with a bit of weakness on some electron pairing of the hexagonal shape, and some hydrogen sticking off the corners, though I am looking at cooking up graphene with trapped atoms of other elements to make something like graphitic carbon nitride. I have seen that something as simple as dissolving it in sulfuric acid will cause some exchange of those pesky hydrogen atoms with the sulfur atoms in the acid as well as the same occurring with chlorine atoms in hydrochloric acid acid :)

just wondering if a chamber that is heated and an electrical charge is applied to attract the hydrogen and possibly photocatalytic action from a strong strobe light could possible deposit faster rates of graphene onto a desired surface.

also on the original concept of pressure (hammer) I used a press to squeeze vein graphite to make diamagnetic sheets that float over a neomagnet quite nicely, and been thinking maybe not just pressure but rotation in opposite directions using a large acme threaded nut and two machined flat ends *maybe on a lathe* acme threaded rod sections or screws so you have something good to get hold of and really torque down on them to squeeze the graphite between the two ends of the rods or screws while not allowing it to escape due to the walls of the nut to make really pressed discs of the stuff, or making a cap like indention and a rod that fits in it and then use the tail stock on a lathe to press it into the cap while the cap is rotating around on the lathe? idea there is that you are moving it so it should settle into the most compact shape like shaking a box of cereal so that it settles?

Hey Ron ,
I understand everybody is using the liquid to help separate the flakes . The fluid helps to get between the plates and basically break the surface tension .
You're saying the bonds won't remain broken via just brute force , if I'm thinking of it correctly ?

Hi James

Think of separating a pencil line into a thousand pencil lines that would make them 1 to 3 microns thick.

Hi James

Yes , you need the water / Acetone to separate the Graphene and the high speed mixer.

It's just like Doug said , the Graphene flakes are very thin
