Abstract: Ultra-high molecular weight polyethylene (UHMWPE) fibers have received widespread attention due to their excellent properties like high strength, high modulus and low density. However, UHMWPE fibers exhibit poor adhesion with resins resulting from the lack of polar functional groups and high surface inertness, which leads to a limitation of the application in the field of composite materials.The interfacial properties can be effectively increased by surface modification. Firstly, this review examines the recent research on the surface modification of UHMWPE fibers, and introduces the interfacial properties and mechanism of fiber reinforced polymers (FRP). Then, it summarizes the findings of current treatments to improve interfacial adhesion, including plasma treatment, radiation-induced surface grafting, oxidation etching, corona discharge and coating. Besides, it discusses the pros and cons of each modification method. Finally, future development is proposed.

摘要: 超高分子量聚乙烯(UHMWPE)纤维因具有高强高模低密等优异性能而受到广泛关注,但由于纤维表面惰性大、缺乏极性基团,导致其与树脂基体的黏结力低,限制了其在复合材料领域中的应用,因而需通过表面改性来提高其界面性能。本文综述了UHMWPE纤维表面改性的最新进展,介绍了UHMWPE纤维增强复合材料的界面性质及增强机理;概述了等离子体改性、辐照接枝改性、氧化刻蚀以及电晕改性和涂层改性等方法,并分析了这些技术的优势和局限性;最后,提出对UHMWPE纤维未来研究方向的展望。
