Abstract | High-performance natural plant fibers reinforced polymer biocomposites with excellent friction and wear properties hold significant practical applications in industry. Unfortunately, it remains a major challenge to engineer the interfacial interactions between the fibers and the polymer matrix, which determines the mechanical and wear properties of the final composites. Herein, we engineer the coir fiber surface by depositing polyethylenimine (PEI) and graphene nanosheets and then prepare the polypropylene/coir fiber biocomposites. As compared with unmodified coir fibers, graphene decorated coir fibers can remarkably reduce the friction and wear, with the lowest friction coefficient at 0.19 and wear rate at 3.5 × 10–7 g/r. The excellent friction-reducing and wear-resistance performances are mainly attributed to three factors, namely the enhanced interfacial bonding, optimized crystallinity, and the formation of a transfer film. The transfer film is comprised of a polypropylene, PEI, and graphene nanosheets. This work provides a facile methodology for the design of high-performance polymer biocomposites with enhanced friction and wear behaviors. The results can also contribute to expand the practical applications of polymer biocomposites in industry. |
