Abstract
A method of surface modifying graphene is disclosed and includes placing powder-like graphene into a closed container, heating up to a preset impurity detaching temperature higher than 100° C. so as to detach the impurity from the surface of graphene, further adjusting the treatment temperature to a preset surface modifying temperature, and injecting the gaseous surface modifying agent to be physically adsorbed by the surface of graphene. Thus, surface modified graphene is formed. The surface modifying temperature is higher than the sublimation temperature of the surface modifying agent and less than the decomposition temperature of the surface modifying agent. Therefore, the present invention is simpler and safer because of only physical adsorption used and no chemical reaction involved. Dispersibility of surface modified graphene in the solution is greatly increased to improve uniformity and enhance the performance of the final product formed of surface modified graphene.
