A process for preparing a completely delaminated graphene oxide/rubber nanocomposite. The process combines emulsion compounding with flocculation or spray drying, retains the morphology of graphene oxide/rubber composite in a liquid state, and achieves highly dispersed and highly delaminated morphology dispersed on nano scale. Furthermore, a substance able to produce ionic bonding or chemical bonding with the surface functional groups of graphene oxide is added to graphene oxide/hydrosol, as a surfactant, thus the interfacial bonding between graphene oxide and the rubber is increased. The composite is subjected to subsequent compounding and vulcanization to prepare a vulcanizate with dynamic performance, such as a high tensile strength, stress at a definite elongation, tearing strength, etc. |
