摘要(Abstract)：

酰胺类溶剂的分离回收与处理是工业领域中一个亟待解决的重要问题，采用渗透汽化（PV）技术分离该体系时，所采用的高分子膜材料需要有较好的溶胀性和耐久性。采用两步法制备了一种均苯型聚酰亚胺膜，通过测试不同单体配比下制备的膜的溶胀性及拉伸强度考察其耐溶剂性能。研究结果表明：当均苯四甲酸二酐（PMDA）与二氨基二苯醚（ODA）摩尔比为1.018：1时，聚酰亚胺膜的溶胀度在30%以下，拉伸强度损失小于20%；制备的PMDA-ODA/Al₂O₃型复合膜，在40℃时，渗透汽化分离DMF/H₂O（（90/10）%（wt））和DMAc/H₂O（（90/10）%（wt））体系的渗透通量分别为149.4和59.0 g·m^-2·h^-1，分离因子分别为21.5和187.1，具有较好的分离效果；复合膜连续运行100 h数据表明，DMAc/H₂O体系渗透通量稳定在210 g·m^-2·h^-1左右，分离因子保持在15左右，具有较好的稳定性。
