    摘要: A composition for manufacturing the inner liners and inner tubes of tires, and a method of preparing the same. The composition includes the following two phases: A) a continuous phase of a composition of graphene oxide/rubber including graphene oxide, a reactive rubber, and a solid rubber; and B) a dispersion phase of an epoxy natural rubber or a thermoplastic resin. In the composition of graphene oxide/rubber, the graphene oxide leads to low gas permeability and remarkably reinforces the rubber composition. The epoxy natural rubber or thermoplastic resin is dispersed in the composition of graphene oxide/rubber and forms an islands-in-the-sea structure. The composition has low gas permeability, excellent mechanical properties, and flexibility, and is adhesive to adjacent rubber.

    摘要: 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.
