中文摘要：
以新型耐高温工程塑料酚酞基聚芳醚酮（PEK—C）为膜材料，N，N-二甲基乙酰胺为溶剂，研究非溶剂添加剂草酸对铸膜液体系热力学性质和凝胶速率的影响，并考查添加剂草酸浓度对成膜结构与性能的影响，对草酸在PEK—C／DMAc铸膜液体系中的作用规律进行深入探讨，
英文摘要：
PEK- C microporous membranes were prepared by phase inversion method using dimethylacetamide （DMAc） as solvent and oxalic acid （OA） as additive. The effect of oxalic acid （OA） additive as a pore - former on the structure and permeation properties connected with the changes of thermodynamic and kinetic properties during the phase inversion process was investigated, and the correlations between the final membrane structure/ permeation properties and thermodynamic/kinetic properties of membrane - forming system are discussed based on the conclusions drawn from the study of oxalic acid＇s influence.
