摘要: 以新型耐高温工程塑料一含酚酞侧基的聚芳醚砜(PES-C)为膜材料,N,N-二甲基乙酰胺(DMAc)为溶剂,通过改变铸膜液中添加荆草酸的含量,采用相转化法在平板刮膜机上制备了一系列超滤膜,考察了添加荆草酸含量对铸膜液粘度、凝胶速度、膜性能和结构的影响,研究了PES-C/DMAC体系中添加荆草酸作用的规律。Abstract: Polyethersulfone with Cardo(PES-C) is a developed engineering thermoplastic and membrane material with high glass transition temperature.PES-C ultrafiltration membranes were prepared by phase inversion method using dimethylacetamide(DMAC) as solvent and o
