Abstract:
1. A method of making a nanocomposite, comprising: adding sulphuric acid solution to a natural graphite to oxidize the natural graphite to create a solution 1; adding potassium permanganate to the solution 1 to make solution 2 and maintaining the temperature of solution 2 below 20° C.; stirring the solution 2 for 1 hour at 35° C.; washing the solution 2 with a hydrogen peroxide and water; filtering the solution 2 to isolate a graphene oxide; drying the graphene oxide at 80° C. to obtain a dry powder of graphene oxide; and mixing the powder of graphene oxide in a specific ratio with a styrene and methyl methacrylate mixture, and stirring and sonicating for an hour to make a suspension, wherein the weight ratio between styrene and methyl methacrylate is 1:1.
