Abstract: It remains a huge challenge to realize the homogeneousgraphenedispersion inelastomermatrix by a simple and general compounding method. Herein, we develop a straightforwardslurrycompounding method for preparation of rubber/graphene composites with well-dispersed graphene. Specifically, TPG (teapolyphenolreduced graphene)/ethanol slurry was first collected bysolventexchange after the reduction ofgraphene oxideby tea polyphenol and then directly melt compounded with chlorosulfonatedpolyethylene(CSM) in a two-roll mill to produce the composites. As revealed by the XRD and morphological studies, TPG homogeneously dispersed in CSM matrix, which together with the strong interfacial interaction between TPG and CSM contribute to the remarkable improvement in mechanical properties of the resulted composites. We envision that the present work offers a straightforward yet effective methodology for preparing high-performance elastomer/graphene composites via conventional melt compounding.
