摘要：

以聚氯乙烯(PVC)和醋酸纤维素(CA)为膜材料，采用非溶剂致相分离(NIPS)法，通过改变纺膜参数制备了PVC中空纤维膜。结果表明：所制得的中空纤维膜具有致密皮层，断面为海绵孔与指状孔共存结构，纯水通量可达314 L/(m2.h)，BSA截留率可达95.0%，断裂强度22MPa。此外，细中空纤维膜可在0.6MPa压力以下稳定运行，并可对自来水中的有机物深度脱除49.30%。

The PVC-CA hollow fiber membranes were prepared by the non-solvent-induced phase separation (NIPS) method using polyvinyl chloride (PVC) and cellulose acetate (CA) as membrane materials and by changing the spinning parameters. The characterization results showed that the hollow fiber membranes had a dense skin layer, a cross-sectional structure of sponge pores and finger pores, a pure water flux of 314 L/(m2.h), a BSA retention rate of 95.0%, and a fracture strength of 22 MPa. In addition, the fine hollow fiber membranes could operate stably under 0.6 MPa pressure and could remove 49.30% of organic matter from tap water.
