| titleOfInvention | A kind of method for preparing hydrophilic charged composite hyperfiltration membrane |
| abstract | The present invention relates to a kind of method for preparing hydrophilic charged composite hyperfiltration membrane, acrylamide AM, acrylic acid AA, the methyl propane sulfonic acid AMPS of 2 acrylamido 2 are dissolved in into film liquid together with macromolecule masking material, to into adding initiator in film liquid, trigger Raolical polymerizable and high-molecular copolymer additive is generated in into film liquid, the high-molecular copolymer additive hydrophily is strong and band bear is electric, is easily dispersed and dissolves in into film liquidï¼›It is described that composite hyperfiltration membrane is prepared into using non-solvent induced phase separation process containing high-molecular copolymer additive into film liquid, high-molecular copolymer additive is embedded into membrane structure, the various hydrophilies and charged functional groups of introducing are not easily runed off.The method for preparing hydrophilic charged composite hyperfiltration membrane of the present invention, film has been embedded in hydrophily by force and the high-molecular copolymer additive molecule with bear electrical property, hydrophily, membrane flux and the contamination resistance of milipore filter, and consistency of performance stabilization can be effectively improved. |
