摘要:
作为聚苯硫醚（PPS）的结构改性物，聚芳硫醚砜（PASS）具有优异的机械性能、耐高温性、尺寸稳定性、耐腐蚀、阻燃和优良的电性能等。由于PASS本身具有的优势，使其在环保、军工、电气、机械、航空等领域具有很好的应用前景。目前国内PASS的合成技术日趋成熟并有望在近年内实现工业化生产。总结了近年来国内尤其是四川大学在PASS基本特性、改性和应用等方面的研究进展：(1)针对PASS在NMP溶液中的不稳定现象，发现并研究了PASS/NMP的结晶溶剂化物。对其形成的过程、结构及结晶行为进行了系统的研究。(2)通过复配助剂以及PPS的引入很好地改善了PASS的熔体稳定性和流动性，改善了其熔融加工性，并对PASS/PPS共混体系进行了深入研究。合理控制加工工艺，成功地制备了性能优良的PASS/连续纤维复合材料。(3)探究氧化处理后PASS分离膜的耐溶剂性，通过配方和工艺的改进制备出一系列不同孔径和结构的PASS耐腐蚀分离膜，通过引入改性纳米二氧化钛成功地制备了抗污染PASS分离膜。这些研究为PASS的产业化应用打下了坚实的基础。
Abstract:
As a chemical structurally modified substance of polyphenylene sulfide (PPS), Poly (arylene sulfide sulfone) (PASS) exhibits outstanding mechanical properties, heat resistance, dimensional stability, corrosion resistance, flame retardancy and electrical properties, etc. Because of the superiority, PASS has a good application prospect in the fields of environmental protection, military industry, electrical, machinery and aviation. This review introduced the physical properties, melt modification and membrane preparation of PASS: (1) PASS/NMP crystal-solvent was discovered from the unstable phenomenon. And its formation, structure and crystallization behavior was studied systematically; (2) With the addition of PPS and compounding processing aids, the melt stability and fluidity of PASS were improved dramatically, which made it suitable for melt processing. The morphology of blends of PASS/PPS was studied at the same time, and the continuous fiber reinforced PASS composites were successfully prepared. (3)The solvent resistance of post-oxidated PASS membrane was explored. By adding various additives, PASS membranes with different pore size and cross-section morphology were prepared. Also antifouling PASS/TiO2 hybrid membranes were made via introducing PAA modified TiO2 nano-particles.
