Abstract

Inspired by natural nacre, hierarchically structured graphene oxide (GO) composite coatings reinforced with different concentrations of polyvinyl alcohol (PVA) were fabricated for development of novel protective surface coatings. It was found that the tribological performance of the GO coating deposited on 304 stainless steel could be significantly improved by including PVA in the coating. The GO/PVA composite coating showed a low friction coefficient of 0.085 and a significant reduction in wear rate compared to that of the GO coating. It was determined that incorporation of PVA between the GO layers enhanced the durability of the coatings. These results showed that PVA can be effectively used as a reinforcing agent of hierarchically structured GO coatings for low friction and wear applications.
