研究了聚苯硫醚/二苯砜体系的热力学相图,探讨了热致相分离法制备耐高温、耐溶剂的聚苯硫醚多孔膜的可能性,并就聚苯硫醚与二苯砜的组成比以及降温速率对多孔结构形成的影响规律进行了讨论。
The thermodynamic phase diagram of polyphenylene sulfide / diphenyl sulfone system was studied. The possibility of preparing polyphenylene sulfide porous membrane with high temperature resistance and solvent resistance by thermal phase separation was discussed. The compositional ratio and the effect of cooling rate on the formation of porous structure were discussed.
