Polyethersulfone with cardo was a developed engineering thermoplastic and membrane material with high glass transition temperature,PES-C ultrafiltration membranes were prepared by phase inversion method using dimethylacetamide as solvent and oxalic acid and polyethylene glycol as additives.The membrane morphology forming and evolution could be observed by the experimental system and method.The effect of additive and polymer concentration on cast solution and the gelation kinetics of polyethersulfone with cardo asymmetric membrane were studied.

采用耐高温工程塑料——含酚酞侧基的聚芳醚砜为膜材料，草酸和聚乙二醇为添加剂， N，N -二甲基乙酰胺为溶剂，并利用改进的凝胶动力学实验装置和方法，使之能真实地再现不同膜孔结构生长及发展演化的过程，借助相关软件对图像进行处理，考察了添加剂、聚合物浓度对铸膜液凝胶速度的影响，对酚酞基聚芳醚砜非对称膜的凝胶过程的动力学进行研究。
