摘要：

以聚间苯二甲酰间苯二胺（PMIA）为膜材料，H2O和CaCl2为混合添加剂，采用L-S相转化法制备PMIA基超滤膜，并分别考察了H2O和CaCl2浓度对超滤膜的孔结构、孔隙率、水渗透通量以及对葡聚糖截留性能的影响规律.结果表明，引入适量H2O作为助溶剂，会提高CaCl2在DMAc溶剂中的溶解度，降低溶剂与非溶剂的交换速率，延迟相分离使得膜形成更发达的海绵状孔和直通型指状孔结构，因而具有较高的孔隙率、纯水渗透率以及葡聚糖截留率；同样，向铸膜液体系中加入适量的CaCl2，离子-偶极作用会破坏PMIA分子间的氢键，因增加了铸膜液的热力学稳定性而延迟相分离.当H2O的添加质量分数为10%，CaCl2为4%时，所制备PMIA超滤膜的孔隙率高达73.7 %，纯水渗透率为16 970 L/(m2·h·MPa)，同时对相对分子质量为150 000葡聚糖的截留率为90.5%，BSA截留率为98.9%，展现出良好的应用前景.

In this work, ultrafiltration membranes derived from poly(m-phenylene isophthalamide) (PMIA) were prepared using L-S phase inversion method with H2O and CaCl2 used as mixed additives. The effects of H2O and CaCl2 concentrations on the pore structure, porosity, water flux, and dextran retention performance of the ultrafiltration membranes were investigated, respectively. Results showed that the introduction of an appropriate amount of H2O as a cosolvent can enhance the CaCl2 solubility in the DMAc solvent, and reduce the exchange rate between solvent and non-solvent and delay phase separation, resulting in the formation of more developed sponge-like pores and straight finger-like pore structures and membranes with high porosity, high water flux and dextran retention rate. Similarly, adding an appropriate amount of CaCl2 to the casting solution can increase the thermodynamic stability of solution and also delay phase separation, since the ion-dipole interaction may disrupt the hydrogen bonds between PMIA molecules. With adding 10% (mass fraction) H2O and 4% CaCl2, the porosity of the prepared PMIA ultrafiltration membrane was as high as 73.7%, the pure water flux was 16 970 L/(m2·h·MPa), and the retention rate of 150 000 glucan and BSA were 90.5% and 98.9%, respectively. The prepared PMIA ultrafiltration membranes show a good application prospect.
