摘　　要：杂环芳纶是指主链中含有芳杂环(通常为苯并咪唑)的一类对位芳纶,其具有轻质、高强高模、高耐热、耐溶剂等优异性能。相比典型的芳纶Ⅱ纤维,杂环芳纶具有更加优异的力学性能,目前在我国的航空航天和防弹防护等领域得到了实际的应用。然而,与其他有机纤维类似,杂环芳纶由于表面惰性,其与树脂的复合性能相对较低,限制了其在先进复合材料领域的应用。本文从杂环芳纶表面改性和结构设计两方面出发,总结近年来提高杂环芳纶复合性能的设计思路、技术手段和研究成果,展望其在先进复合材料应用领域的发展趋势,为有机纤维的界面设计及改善界面粘接性提供帮助和参考。Heterocyclic aramid refers to a type of para-aramid containing aromatic heterocycles(usually benzimidazole units)in the main chain,which has excellent properties of lightweight,high strength and modulus,high thermal resistance and good solvent resistance.Compared to the typical aramid fiberⅡ,heterocyclic aramid exhibits superior mechanical properties and has been practically applied in the fields such as aerospace and bulletproof protection in China.However,similar to other organic fibers,the composite performance of heterocyclic aramids with resins is relatively low due to their inert surface,which limits their application in the field of advanced composite materials.This article from two aspects of surface modification and structural design,the design ideas,technical means and research results to enhance the composite performance of heterocyclic aramids in recent years are summarized,and the development trend of its application in the field of advanced composite materials is forecast,so as to provide assistance and reference for the interface design and improvement of interfacial adhesion of organic fibers.
