制备聚酰亚胺不对称膜的新方法

A New Method for Preparation of Polyimide Asymmetric Membrane

叙述了一种用成形的聚酰胺酸不对称膜亚胺化来制备聚酰亚胺不对称膜的方法，利用红外、扫描电镜和水通量作为表征手段，从亚胺化效果。

A new method for the preparation of polyimide asymmetric membrane from polyamicacid asymmetric membrane has been developed.The membrane structure was studied by IR,SEM and water flux,the effect of imidization conditions on membrane performance was discussed.
