摘要(Abstract):
综述了内部和外部凝固剂的化学性质、凝固浴温度等对聚酰亚胺(P)I中空纤维的形态和对PI中空纤维膜的气体分离性能的影响。同时,叙述了纤维塑化抑制和亚胺化条件控制等对提高PI中空纤维膜分离性能的作用。
The profound effects of the chemical properties of inner and external coagulants and coagulation bath temperature on polyimide hollowfiber morphology and gas separation performance were discussed. Furthermore, the influences of different heat -treatments, crosslinking and the suppression of the fiber plasticization on gas separation were also reviewed.
