摘要： The dispersion behaviors of graphene oxide (GO) and poly(sodium p-styrenesulfonate) (PSS) modified silica doped into the natural rubber (NR) matrix are revealed in this study, respectively. The NR composites are fabricated by latex compounding technology. We find that GO as a two-dimensional dispersant can link with silica through its oxide groups and form a layer of silica on the surface, which improves the silica distribution homogeneity. In comparison, PSS as a one-dimensional dispersant twins silica particles and forms a matrix consisting of stick-like composite with fillers. Both GO and PSS can improve the dispersibility of silica in the NR composites, and the tensile and tear strengths of the NR/GO/SiO2 and NR/PSS/SiO2 are improved compared to those of the NR/SiO2 composites. This strategy of modifying silica with GO and PSS is proven being an effective approach for the development of elastic nanocomposites. (C) 2016 Society of Plastics Engineers
