Effect of Graphene Oxide on Anti-aging Property of Nitrile Butadiene Rubber

Abstract

The blends with higher damping performance was prepared based on nitrile butadiene rubber(NBR) with addition of graphene oxide(GO) and modified graphene oxide(MGO) prepared by improved Hammer method. Meanwhile, the damping property and the anti-aging property of the blends were investigated by DMA, AFM, SEM and so forth. The results show that after the addition of the GO and MGO, the tangent of loss angle(tanδ) increases and also the anti-aging property is improved. When adding less amount of GO in the matrix, the anti-aging property is better; when adding MGO in the matrix, the amount of addition is not obviously related with the anti-aging property of the blends. The dispersion of GO and MGO has positive correlation with its anti-aging property. By microscopic analysis, the main reason for the decrease of anti-aging property of the blends is the agglomeration of the GO. The interface effect formed by the addition of MGO and GO is the main reason for its high damping property and anti-aging property.
