摘要
介绍了聚对苯撑苯并双噁唑(PBO)纤维的热分解行为、热分解机理、水解稳定性、光稳定性及化学稳定性等方面的研究进展。PBO纤维的热稳定性和化学稳定性优良,其水解稳定性和光稳定性较差。通过热处理可提高PBO纤维的强度和模量。指出应进一步研究PBO纤维的稳定性,提高其性能,扩大应用领域。
The research progress in the thermal decomposition behavior, thermal decomposition mechanism, hydrolytic stability, photo stability and chemical stability of poly（ p-phenylene benzobisoxazole） （PBO） fiber was introduced. PBO fiber showed excellent thermal and chemical stability and poor hydrolytic and photo stability. The strength and modulus of PBO fiber can be improved by heat treatment. It was put forward that the stability of PBO fiber should be studied further to improve the properties and develop the application field.
