I experimented with Graphene as part of my engineering thesis at uni back in 2010. I was trying to synthesize anode materials for Li-Ion battery applications. The idea being graphene would better accommodate volume expansion during intercalation leading to better cycling performance of the battery.
I don't think there is any particular "secret sauce" in the technique I was using to make the graphene - I was using Modified Hummer's method (MH method) to make graphene-oxide and then reductive precipitation (RP) - it's well covered by the literature. There is even a wikipedia article on it.(https://en.wikipedia.org/wiki/Hummers%27_method https://en.wikipedia.org/wiki/Hummers%27_method). I don't think anything would really stop a dedicated amateur.
I agree with you a lot of the difficulty is sourcing the chemicals and especially the equipment (sonicator, centrifuge etc) which makes it much more suited for a laboratory than amateur experimentation. Also agree it's slow and time consuming to produce at least using method I was.
