中文摘要:
      利用聚酰胺膜表面未反应的酰氯基团,采用间苯二胺(MPD)或聚乙烯亚胺(PEI)作为连接剂,环氧丙醇作为改性剂,对聚酰胺膜抗污染性能进行了研究。结果表明:(1)以双氨基MPD(1.0%)为连接剂、0.2%的环氧丙醇改性膜的接触角降低了14.0°;(2)以多胺基的PEI(0.5%)为连接剂,0.8%的环氧丙醇改性膜的接触角可降低31.7°,抗蛋白污染测试后改性膜的水通量恢复率显著提高。
英文摘要:
      In this paper, taking advantage of unreacted acid chloride groups on the surface of polyamide membrane, use m-phenylenediamine (MPD) or polyethyleneimine (PEI) as linker and glycidol as modifier to prepare modified membrane. The results show that the contact angle of modified membrane prepared by using 1% MPD as linker and 0.2% glycidol as modifier is reduced by 14°; the contact angle of modified membrane prepared by using 0.5% PEI as linker and 0.8% glycidol as modifier is reduced by 31.7°. And the flux recovery rate of modified membrane is markedly improved after antifouling test.
