C25B 9/00

Abstract:

A method of synthesizing high quality graphene for producing graphene particles and flakes is presented. The engineered qualities of the graphene include size, aspect ratio, edge definition, surface functionalization and controlling the number of layers. Fewer defects are found in the end graphene product in comparison to previous methods. The inventive method of producing graphene is less aggressive, lower cost and more environmentally friendly than previous methods. This method is applicable to both laboratory scale and high volume manufacturing for producing high quality graphene flakes.
