▎ 摘　　要

NOVELTY - A silane-functionalized graphene is prepared by mixing graphene nanoplatelets and organic peroxide in dihydrolevoglucosenone solution at room temperature to 60 degrees C; mixing alkoxysilane in the solution at 60-90 degrees C; sonicating the solution with ultrasonic waves; washing the solution with polar solvent; and drying the solution where the dried solution are alkoxysilane functionalized graphene powder. USE - Preparation of silane-functionalized graphene. ADVANTAGE - The method is simple with low reaction condition requirement. The graphene modified by alkoxysilane coupling agent can be obtained without catalyst or toxic chemical.
