摘　　要：超高分子量聚乙烯(UHMWPE)纤维因具有高化学稳定性,高机械性能和低成本等优点而成为理想增强材料之一。然而,规整的非极性分子链结构致使UHMWPE纤维结晶度高、与树脂基体之间几乎无化学键合,本文因而与树脂的粘合性差。为此已经进行了许多纤维表面处理的工作,如紫外辐射、等离子体处理、聚合物涂层等。主要从湿法化学改性和干法化学改性这两方面入手,总结归纳了目前超高分子量聚乙烯纤维的界面改性研究现状,从物理和化学两个方面揭示界面增强机理以及界面性能与复合材料力学性能的关系,为超高分子量聚乙烯纤维的界面结构设计和改性提供科学理论依据和技术指导。Ultra-high molecular weight polyethylene(UHMWPE)fiber has become one of the ideal reinforcement materials due to its high chemical stability,high mechanical properties and low cost.However,the regular non-polar molecular chain structure results in the UHMWPE fiber with high crystallinity and almost no chemical bond with the resin matrix,so the adhesion to the resin is poor.For this reason,many fiber surface treatments have been carried out,such as ultraviolet radiation,plasma treatment,polymer coating and so on.This article mainly starts from two aspects of wet chemical modification and dry chemical modification,summarizes the current research status of interface modification of ultra-high molecular weight polyethylene fibers,and reveals the interface enhancement mechanism and interface performance from both physical and chemical aspects.The relationship with the mechanical properties of composite materials provides scientific theoretical basis and technical guidance for the design and modification of the interface structure of ultra-high molecular weight polyethylene fibers.
