To study the influence of modified graphene(MGN/HDPE ) composite on crystal behavior of high density polyethylene, graphene (GN) and MGN were prepared by chemical oxidation-reduction, followed by the preparation of GN/HDPE and MGN/HDPE composites with melt blending method. The structures of GN and MGN were characterized by FTIR, the crystallization of composites were analyzed by DSC. The non-isothermal crystallization kinetics of samples were extensively studied by Mo's equation. The results show that stearic acid has been successfully grafted onto the GN, and MGN displays restraining the crystallization of HDPE much more strongly than GN.
