Abstract
Graphene nanoplatelets (xGnP-C) with specific surface areas varying from 300 to 750 m2/g were investigated as novel reinforcing fillers for carboxylated acrylonitrile- butadiene rubber (XNBR). The effects of graphene nanoflakes loadings up to 15 parts per hundred rubber (phr) on the rheometric characteristics, stress-strain behavior, crosslink density (ν), resistance to UV radiation and thermo-oxidative aging of the XNBR/ZnO/graphene xGnP-C composites were investigated. Substantial improvement in the mechanical properties of XNBR with increased contents of xGnP-C filler was achieved. It was found that the addition of 5 phr of graphene significantly increased UV stability, tensile strength (TS) and modulus at 100%, 200% and 300% elongation of rubber material. The effect was more pronounced for composites containing graphene with the highest specific surface area 750 m2/g. The chemical information on the functional groups on the xGnP-C surface was obtained by X-ray photoelectron spectroscopy (XPS) method. In this case, the reinforcing effect of graphene xGnP-C may result from an additional chemical bonding which is possible between the -COOH groups of the rubber and the reactive, oxygen-containing groups on the filler surface.
