Abstract

This application relates to natural rubber (NR) composites, and more specifically to a method of preparing a graphene/natural rubber composite. In the method provided herein, nano-silica loaded graphene oxide (SiO-GO) is formed by electrostatic interaction between silica and graphene oxide (GO), and then the SiO-GO is added to natural rubber (NR) latex to obtain a SiO-GO/NR masterbatch by aqueous phase synergistic aggregation-precipitation process. The SiO-GO/NR masterbatch is subjected to mechanical blending and vulcanization to obtain the graphene/NR composite.
