摘      要：Graphene oxide(GO)has recently attracted substantial interest as a possible reinforcing agent for next generation rubber composite *** this research,GO was incorporated in natural rubber(NR)composites through latex co-coagulation *** microstructures of GO/NR composites were characterized through a combination of transmission electron microscope,scanning electron microscope,X-ray diffraction,Fourier transform infrared spectroscopy,and Differential scanning *** results showed that highly exfoliated GO sheets were finely dispersed into NR rubber matrix with strong interface interaction between GO and *** mechanical properties of the GO/NR composites were further *** results showed that the tensile strength,tear strength and modulus can be significantly improved at a content of less than 2 ***,GO exhibited specific reinforce mechanism in NR due to the stress-induced crystallization effects of *** stress transfer from the NR to the GO sheets and the hindrance of GO sheets to the stress-induced crystallization of NR were further displayed in stress-strain behavior of GO/NR *** enhanced properties were attributed to the high surface area of GO sheets and highly exfoliated microstructures of GO sheets in NR.
