超高分子量聚乙烯纤维的研究现状与应用OA

Ultra-high molecular weight polyethylene(UHMWPE)fibers are high-performance fibers pro-duced by specialized processes from polyethylene resin with molecular weights ranging from 1×106 g/mol to 5×106 g/mol.They exhibit outstanding physical properties such as ultra-high specific strength and modulus,low densi-ty,excellent wear resistance and low-temperature tolerance.However,their non-polar molecular structure in-herently presents drawbacks including low surface energy,poor interfacial adhesion,insufficient heat resistance and flammability.In this paper,the physicochemical properties of UHMWPE fibers were briefly introduced,and the current state of domestic and international research on UHMWPE fibers and their application fields was re-viewed.Currently,UHMWPE fibers had expanded into application areas such as electromagnetic wave absorption and shielding materials,flame retardant materials,biomaterials and reinforcing materials.Functional modifica-tions had been employed across these fields to overcome material limitations.Future research should focus on pre-cise control on fiber structure,efficient modification techniques and advanced application system solutions to fur-ther enhance their comprehensive performance and application values.
