摘　　要：聚对苯撑苯并双噁唑(PBO)由于其特殊的表层结构,与聚合物树脂基体复合时存在严重的界面不相容性。简要介绍了PBO纤维的结构与性能,综述了化学刻蚀、偶联剂处理、等离子体处理、电晕处理、辐射处理、酶处理、热处理、化学涂层和超临界液体处理等PBO纤维表面改性方法。The poly-p-phenylenebenzobisthoxazole （PBO） fiber is an organic fiber with very high tensile strength and modulus, and shows great potential in the reinforcement for polymer matrix composites. However, there is poor interfacial compatibikity between the PBO fiber and the polymer matrix due to the surface characters with organic groups and the skin-core structure. Therefore, the surface modification for the PBO fiber attracted more attentions nowadays. In this paper, the structure and properties of the PBO fiber are introduced in brief, and research progresses on surface modification technologies, such as the chemical treatment, coupling agent, plasma coating, corona treatment, radiation treatment, heat treatment, enzymatic surface modification, heat treatment and supercritical fluid to the PBO fiber are reviewed.
