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. © 2018, Editorial Board of Polymer Materials Science & Engineering. All right reserved.
