Abstract

This chapter gives a brief survey on the dry sliding wear performance of rubbers with and without coatings that contain novel "micro- and nanofillers". In addition, concepts for the rubber "nanostructuring" were introduced and preliminary results on the sliding wear characteristics of such nanostructured systems were reported.Incorporation of micronized powders of poly(ether ether ketone) and poly(tetrafluoro ethylene) did not improve the resistance to wear due to lack of adhesion to the rubber matrix. Carbon nanofibers, nanotubes and layered graphite proved to be more efficient tribological "nanoadditives" than organoclays. "Nanostructuring" by creation of interpenetrating network-like structures is a promising method to tailor the tribological performance of the related rubber-based hybrids. It was also underlined that the dry friction and wear characteristics of nanoreinforced and nanostructured rubbers strongly depend on the type and testing conditions of the related tribotests. Based on the actual research activities some future trends for the development of rubbers with improved resistance to sliding wear were deduced.
