摘要:
以均苯四甲酸二酐(PMDA)和4, 4′二氨基二苯醚(ODA)为主要单体，亲水气相纳米二氧化硅(SiO2)为改性试剂，通过溶液聚合和亚胺化分别制备出聚四氟乙烯(PTFE)/聚酰亚胺(PI)和SiO2/PI/PTFE两种复合膜。利用傅立叶红外光谱仪(FTIR)、热场发射电子显微镜(SEM)、热重分析法(TGA)、接触角测试和渗透汽化测试研究改性前后膜结构及渗透汽化性能的变化。结果表明：PI/PTFE复合膜的渗透通量和分离因子在料液温度为30～60 ℃ 时，随温度的升高而分别提高，在渗透侧压为20～1000 Pa时，随渗透侧压的升高而分别降低；当亲水气相纳米二氧化硅的浓度达到3%质量分数时，制备的SiO2/PI/PTFE复合膜对95%质量分数的乙醇/水混合液的分离效果在通量及分离因子方面达到0.352 kg/(m2·h)、62.90。
