摘要:

作為聚苯硫醚（PPS）的結構改性物，聚芳硫醚砜（PASS）具有優異的機械性能、耐高溫性、尺寸穩定性、耐腐蝕、阻燃和優良的電性能等。由于PASS本身具有的優勢，使其在環保、軍工、電氣、機械、航空等領域具有很好的應用前景。目前國內PASS的合成技術日趨成熟并有望在近年內實現工業化生產�？偨Y了近年來國內尤其是四川大學在PASS基本特性、改性和應用等方面的研究進展：(1)針對PASS在NMP溶液中的不穩定現象，發現并研究了PASS/NMP的結晶溶劑化物。對其形成的過程、結構及結晶行為進行了系統的研究。(2)通過復配助劑以及PPS的引入很好地改善了PASS的熔體穩定性和流動性，改善了其熔融加工性，并對PASS/PPS共混體系進行了深入研究。合理控制加工工藝，成功地制備了性能優良的PASS/連續纖維復合材料。(3)探究氧化處理后PASS分離膜的耐溶劑性，通過配方和工藝的改進制備出一系列不同孔徑和結構的PASS耐腐蝕分離膜，通過引入改性納米二氧化鈦成功地制備了抗污染PASS分離膜。這些研究為PASS的產業化應用打下了堅實的基礎。

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.
