摘要：
Tribological tests of polymeric composite materials based on UHMWPE modified with inorganic nanoparticles and brominated UHMWPE as a functional alloying element have been performed in order to establish their effect on the interphase interactions in a UHMWPE/nanoparticles system. The wear resistance of the polymer with brominated UHMWPE is shown to be 8-10 times higher than that of the initial polymer, most likely due to the formation of dissipative structures on the polymer surface, which are formed by the chemical and adhesive cross-linking of nanoparticles and tribodecay products.
