Title The research of the properties of SBR/xNBR hybrids reinforced by graphene oxide
Abstract
In this paper, the graphite oxide was carried out by Hummers method, and then exfoliated in water via ultrasonication to smash and release to form graphene oxide. The graphene oxide was added to the carboxyl nitrile (xNBR) and styrene-butadiene (SBR) blended latex, and then manufacture vulcanizate through curing. We studied the dispersion of graphene oxide in SBR / xNBR composite, as well as the effects of graphene oxide on the curing properties, mechanical properties, thermal conductivity, thermal stability of composite.The results show that, graphene oxide which was prepared via oxidation of graphite (Hummers method) and followed by ultrasonication had many different functional groups. The optimum curing time was obviously decreased and the tear strength, thermal conductivity, thermal stability of sample were unparallelly improved with the loading of GO increased. When the content is 3 phr, the maximum tensile strength was obtained, which was 18.31MPa and 358.9% higher than unfilled sample.
