讨论了纳米无机小分子物质TiO2、SiO2、Al2O3对PVC/PVDF/PMMA共混溶液的剪切黏度及其共混膜形态结构、水通量及机械性能等性能的影响,结果表明,无机小分子TiO2、SiO2、Al2O3的加入均能使PVC/PVDF/PMMA共混溶液的剪切粘度增加,但TiO2增加的程度最大,SiO2、Al2 O3增加的程度相当；纳米TiO2、SiO2、Al2O3对使PVC/PVDF/PMMA共混膜的水通量和韧性有较大程度的提高,且加入量为2％时,提高程度最大；SiO2、Al2O3对共混膜的结构有一定程度的影响,并使共混膜的拉伸强度略有降低,TiO2的加入对膜的结构没有太大的影响,但能使共混膜的拉伸强度略有提高.
