You can buy my book Graphene 101 An Inventors guide to making graphene at https://www.smashwords.com/books/view... the money will help my research. thanks. The improved audio version of this video is at http://youtu.be/lRDPZ8yLh04 i have kept this one because of the tons of good info posted by others.
Graphene is the big material of the moment and indeed it does some pretty amazing things that could be very useful in free energy research - for example charging a capacitor made from graphene in seconds and discharging it to do work in minutes. All good stuff. But the first thing to do is to make it. So, i decided to give it a go - here is the method i used
Modified Hummer's Offeman Method
A) Low Temperature Stage
1) 5g Graphite 115mL H2SO4 (98%) 2.5g NaNO3
mix in an ice bath for 30 mins
2) 15g KMnO4
Slowly add, while stirring, over one hour. Stir for an additional hour keeping the temp below 5oC.
B) Mid Temperature Stage
Raise temperature to 45oC and stir for one hour.
C) High Temperature Stage
230mL distilled water
Add 230mL water. Stir 30 for mins at 45oC
600mL distilled water
150mL H2O2 (9%)
add to mix
Wash in 5% HCL then distilled water. Dry
Add dried cake to 50mL of water and stir. Leave for 24 hours and filter. Discard filtrate. Solution is GO in water.
This video shows how to make graphene oxide - but it's nearly there and what i want to do next is make a sonication reaction chamber to further process it. So that's what i am going to do next - but i wanted to share with you how far i had got.
