摘　　要：芳香族聚酰胺纤维因具有高强高模、轻质耐热、抗冲耐磨等优势,被广泛应用于军民两用领域。由于分子结构中存在大量的生色基团,芳香族聚酰胺纤维易吸收紫外辐射而引发不可逆的光老化损伤,制约其使役性能。本文概述了芳香族聚酰胺纤维的紫外光敏特性,分析总结了其光老化机理,并重点介绍了目前抗紫外老化的主要改性研究方法。Aromatic polyamide fibers have broad applications in military and civilian fields,due to their excellent advantages such as ultrahigh strength and modulus,light weight,heat-resisting,impact and fatigue resistance.However,owing to the large number of chromogenic groups in the molecular structure,aromatic polyamide fibers easily absorb ultraviolet radiation and cause irreversible photo-aging damage,which restricts their service performance.This paper summarizes their ultraviolet sensitivity characteristics,photo-aging mechanism,and highlights the current main anti-ultraviolet aging modification methods.
