摘　　要：以玻璃化温度高、强度大、易磺化和耐酸碱的带酞侧基的聚芳醚酮(PEK-C)为支撑膜材料,研究了PEK-C铸膜液组成及复合液配比等对PFT反渗透复合膜(PFT ROCM)制备及其脱盐功能的影响。 试剂与材料 糠醇(FA):化学纯。用前精制,三(2-羟乙基)异氰尿酸酯(THEIC)。熔点134～136℃。聚乙二醇-400(PEG-400):化学纯。DMF,DMAc,N-甲基吡咯烷酮(NMP)为分析纯,经脱水精制。异丙醇、硫酸为分析纯。十二烷基磺酸钠(SLS)化学纯。含酞侧基的聚醚醚酮PEK-A polyether reverse osmosis composite membrane 'PFT' was prepared. The supporting membrane was an asymmetric ultrafiltrate membrane made from polyetheretherketone 'PEK-C'. The active layer was a sulfonated closslinked polycondensate made by in-situ polymerization of furfuryl alcohol and tris-(2-hydroxyethyl)isocyanurate. The constitution of the casting solution of PEK-C and the additives to the composite membrane solution on the performance of PFT membrane have been discussed. The title membrane gave over 99. 6% salt rejection and 0. 30m^3/m^2 per day Water flux at pressure of 4.9MPa with 1. 5% NaCl aqueous solution.
