You can buy my book Graphene 101 An Inventors guide to making graphene at the money will help my research. thanks. So, i was getting a lot of people telling me that the method I was using was pretty complicated and I agree. So, I have spent quite a bit of time looking for a much simpler way to do this and I think I have found it. Basically the method is to put\r
\r
320ml Sulphuric Acid\r
80ml Phosphoric Acid\r
3.2g graphite Flake\r
18g Potassium Permanganate\r
\r
into a jar and leave it sitting around for 3-4 days. At the end of that time add 100ml of Hydrogen Peroxide and you are done. What you should have is a bright yellow precipitate of graphene oxide. Then you need to wash this in 1 moar HCl and water until the pH is about 4 or 5. I dont think you could get simpler than this for a wet chemical method that seems to produce nearly 100% graphene oxide - well, I know I dont lead that interesting a life but I am pretty excited by this.
