Abstract: The research progress in wear resistance modification of ultrahigh molecular weight polyethylene(UHMWPE) in recent years was reviewed in this paper. The modification could be divided into two categories: physical blending modification including adding inorganic fillers and/or other polymers; and chemical modification including crosslinking and plasma processing. The modification mechanism and effect of different modifying techniques were discussed. The development trend of wear resistance modification on PE-UHMW was also prospected.

Key words: ultrahigh molecular weight polyethylene, wear resistance, modification, research progress
