| Abstract: | (3-(methaeryloylamino)propyl)-dimethyl(3-sulfopropyl)-ammonium hydroxide(MPDSAH)was grafted on Poly(vinylidene fluoride)(PVDF)chains,which resolved in N-Methyl-2-pyrrolidone and was pre-treated by O-zone.Then the PVDF membranes were prepared by phase inversion methods.The surface morphology of these membranes were characterized by IR,SEM.The hydrophilie of the membranes were tested by contact angle. |
