摘　　要：简述了聚对苯撑苯并双噁唑(PBO)纤维的结构与性能;详述了PBO纤维的改性研究进展。PBO纤维的改性主要是改善其抗压性能和表面粘结性能。提高微纤间相互作用或交联等方法可提高PBO纤维的压缩强度;通过酸处理、偶联剂处理、等离子体处理及电晕处理等方法可提高PBO纤维的表面粘结性能。指出表面改性仍将是PBO纤维改性研究的重点。The structure and properties of poly-p -phenylene benzobisthoxazole （PBO） fiber were described briefly. The research progress in PBO fiber modification was described in details. The principle purpose of the modification was to improve the resistance to compression and surface cohesion property of PBO fiber. The compressive strength of PBO fiber can be enhanced by crosslinking or increasing the interaction between microfibrils. The surface cohesion properties of PBO fiber can be improved by acid, coupling agent, plasma and corona treatments. It was pointed out that the surface modification would be the focus of PBO fiber modification research.
