Method for initiating polymerization of epoxy monomer by using graphene oxide as initiator

Abstract

The invention discloses a method for initiating polymerization of an epoxy monomer by using graphene oxide as an initiator. The method comprises the following steps: the epoxy monomer and the graphene oxide are added to a reaction system, wherein, the mass rate of the epoxy monomer to the graphene oxide is 300-5, the graphene oxide can prompt the epoxy monomer to undergo cationic ring-opening polymerization at the temperature of 0-100 DEG C, and the obtained epoxy polymer can be grafted in situ on the surface of a graphene oxide sheet layer, so that surface modification of the graphene oxide is realized, and cation-initiated polymerization and grafting amount are controlled by reaction time and reaction temperature.
