Graphene Nanoplatelets/Natural Rubber Nanocomposites

The work aims to study effects of adding graphene nanoplatelets on graphene nanoplatelets/natural rubber nanocomposites, and compare mechanical blending with latex blending. The preparation process of composite materials was studied. The morphology, structure and properties of graphene nanoplatelets and graphene nanoplatelets/natural rubber nanocomposites were investigated via scanning electron microscopy (SEM), transmission electron microscope (TEM), Raman difference spectroscopy (RDS) and universal mechanical testing machine. The results show that the properties of the composites were enhanced by the addition of graphene nanoplatelets. And compared with pure rubber, the tensile strength of graphene nanoplatelets (10phr)/natural rubber composites was increased by 41.5%, and the thermal conductivity of composites was increased by 153.3%. Graphenenano platelets can greatly improve the properties of composites. Properties of composites prepared by latex blending method are better than that prepared by mechanical blending.h
