| Abstract: | A composite nanofiltration membrane is fabricated by the interracial polymerization supported on a microporous polysulfone substrate,using PDMAEMA as the prepolymer of the crosslinking reaction. The polyelectrolytes properties of the crosslinked PDMAEMA hydrogel layer are investigated. The results show that the surface of the charged nanofiltration membrane exhibites hydrophobicity. The swelling ratios of the crosslinked hydrogel layers show pH,added salt concentration andtemperate responsibilities. |
