Abstract: The NR/GO nanocomposites were fabricated via latex compounding process with the different lateral size of GO. In this study, the effects of GO lateral size on the rheological performance, the mechanical properties and the morphological structure of NR/GO composites were studied. The results showed that the viscosity of latex filled with large size GO increased to 3 600 mPa·s-1 almost improved 30 times than that of NR Latex (NRL) as of the steric hindrance effect. While the tensile strength and the fracture energy of NR/GO nanocomposites were obviously enhanced by 15% and 25% with only 1% loading of SGO. The morphological structure of NR/LGO composites is layer-layer isolation structure and that of NR/SGO composites is segregated-network structure.

Key words: graphene oxide; rheological properties; mechanical performance; morphological structure
