▎ 摘  要

NOVELTY - Method for obtaining reduced and covalently functionalized graphene oxide with amines involves ultrasonically dispersing an aqueous graphene oxide concentrate, adding a functionalizing agent in alcoholic solution, adding an organic reducing agent in alcoholic solution and keeping the solution in thermal reflux. USE - Method for obtaining reduced and covalently functionalized graphene oxide (claimed). ADVANTAGE - The purpose of functionalization is to impart graphene oxide in organic solvents where it would normally not be, and at the same time improve polymer smoothness, the reduction is intended to increase its electrical conductivity and achieve a 1.1eV optical forbidden energy gap.
