| 摘 要： | 研究酸和碱对聚苯硫醚纤维性能的影响.通过场发射扫描电镜(FESEM)、单纤强力仪和差示扫描量热仪(DSC)对酸、碱处理前后PPS纤维的表面形貌、力学性能和热学性能进行研究.结果表明:NaOH和H2SO4对PPS纤维的性能影响较小;而HCl、HNO3对PPS纤维各种性能的影响较大.经HCl、HNO3处理后PPS纤维表面出现凹槽和裂痕,其断裂强力和断裂伸长率随HCl、HNO3浓度增大和处理时间的延长而降低;经酸碱处理后的PPS纤维的热焓值都有不同程度的下降,其中经HNO3处理后其热焓值降幅最大.

| Abstract: | PPS fibers are treated with four kinds of acids and alkali at different concentrations and time durations.The surface morphology of PPS fibers is studied by FESEM.Their tensile and thermal properties are measured by tensile tester and DSC,respectively.The results show that HCl and HNO3 have obviously detrimental effect on the properties of PPS fibers relative to NaOH and H2SO4.Many cracks and holes appeared on the surface of PPS fibers after HCl or HNO3 exposure.The breaking strength and breaking elongation... |
