The invention discloses rubber chemical reduced and modified
graphene oxide as well as a preparation method and an application thereof. The
graphene oxide can be simultaneously reduced and modified just by conducting a reaction in one step; and specifically, the rubber chemical modified
graphene is prepared by the following steps: mixing
graphite oxide and water, and conducting ultrasonic exfoliation so as to obtain graphene oxide water dispersion liquid; mixing a rubber
chemical solution with the graphene oxide water dispersion liquid, and conducting heating and stirring so as to obtain the rubber chemical modified graphene. According to the invention, a
reducing agent is non-toxic and environment-friendly, the method is simple and easy to implement and
reaction conditions are mild; and the prepared graphene is low in content of an
oxygen-containing functional group in surface and high in conjugation degree; some
rubber chemicals are chemically grafted on the surface of the graphene, so that the uniform dispersion of the graphene in rubber is promoted and an
interface bonding action between the graphene and the rubber matrix is enhanced, and in addition, the migration and volatilization of the
rubber chemicals are prevented and the action efficiency of the
rubber chemicals is improved, so that the performance of a rubber / graphene
composite material is improved. The invention provides a new opportunity and a new way for the green
mass preparation of the graphene and for the preparation of the high-performance rubber / graphene nano
composite material.
