摘　　要：为探索环保型高性能水处理超滤膜材料,设计、合成了仅含碳、氢、氧元素的丙烯酸酯类两亲性共聚物-聚(甲基丙烯酸甲酯-co-丙烯酸丁酯-co-甲基丙烯酸)[P(MMA-co-BA-co-MAA),简写为PMBM],研究了PMBM超滤膜的制备、结构和性能.研究发现,通过非溶剂诱导相转化法(NIPS)制备的PMBM超滤膜具有良好的亲水性和抗污染性,不同羧基含量的PMBM膜在不同pH下的性能差别较大.其中MAA质量分数为11%的PMBM-11膜在中性条件下纯水通量为1310 L/(m^(2)·h·MPa),对BSA的截留率为98%,BSA污染后的通量恢复率(FRR)达到79%.In order to develop an environmentally friendly and high-performance water treatment ultrafiltration membrane materials,the amphiphilic copolymers,poly(methyl methacrylate-co-butyl acrylate-co-methacrylic acid)(P(MMA-co-BA-co-MAA),PMBM),only containing only C,H and O elements were designed and synthesized in this research.The ultrafiltration membranes of PMBMs were prepared via typical non-solvent-induced phase separation(NIPS)process.It is found that suspension polymerization is an effective method to synthesize PMBMs,and the PMBMs can be prepared into ultrafiltration membrane with good pore structure.The carboxyl group in PMBMs can endow the membranes with good hydrophilicity and antifouling property.The performance of PMBM membrane with different carboxyl group content can vary obviously at different pH condition.The membrane of PMBM-11 containing 11%(mass fraction)MAA performed a pure water flux of 1310 L/(m^(2)·h·MPa),a BSA retention rate of 98%,and a flux recovery rate(FRR)of 79%after BSA contamination.
