纳米填料改性聚苯硫醚及其纤维研究进展

摘要

聚苯硫醚（PPS）是一种耐高温、耐化学腐蚀、阻燃的高性能材料，其纤维制品可广泛应用于高温过滤、化学防护等领域。通过纳米填料熔融复合技术，可显著提高 PPS 材料及其纤维的综合性能。详细介绍了国内外纳米填料对 PPS 及其纤维紫外光稳定性、热氧稳定性、结晶和力学性能、以及耐磨性的改性研究，并进一步分析了纳米粒子对 PPS 的改性机理。详述了目前 PPS 纳米复合改性研究的不足，提出相应的解决方案。指出了纳米改性研究首先需要提高 PPS 纤维的紫外光稳定性、耐热氧化性能和最高使用温度，以扩展 PPS 纤维的应用范围。综合分析表明，PPS 纤维的纳米改性研究仍处于起步阶段，需深入对不同形貌、尺寸纳米填料复合改性及纳米复合纤维成形机理的研究，并拓宽其研究范围。%Polyphenylene sulfide (PPS)is a material which has outstanding high-temperature resistance,chemical re-sistance,flame retardance.PPS fibers are widely applied in the field of high temperature filtration and chemical protec-tion.The comprehensive performances of PPS nanocomposites and fibers are further improved which are reinforced by ad-dition of nanoparticles.In this paper,the PPS materials or fibers modified by nanoparticles for improving the ultra-violet resistance,the thermal oxidation resistance,abrasion resistance,the crystallization and mechanical properties,and the modification mechanism of nanoparticles on PPS were analyzed further.The properties of PPS materials which should be continued to improve were also introduced in detail.It was highlighted that the ultra-violet resistance,the thermal oxida-tion resistance and the permitted maximal used temperature of PPS materials should be enhanced for further application. More researches about PPS nanocomposites with different nanotopography and sizes and the formation mechanism of PPS nanocomposites fiber need to be studied.
