| titleOfInvention | Modified polyamide reverse osmosis membrane made of carboxylic acid glycine betaine type colloid nano particles |
| abstract | The invention discloses a modified polyamide reverse osmosis membrane made of carboxylic acid glycine betaine type colloid nano particles. The modified polyamide reverse osmosis membrane is characterized in that a soap-free emulsion polymerization method is adopted to prepare the carboxylic acid glycine betaine type colloid nano particles, the carboxylic acid glycine betaine type colloid nano particles are added in an aromatic polyamine water phase solution for performing interfacial polymerization reaction with aromatic multielement acyl chloride in an organic phase solutio, and the modified polyamide reverse osmosis made membrane of the carboxylic acid glycine betaine type colloid nano particles is prepared; the good hydrophily and stain resistance of carboxylic acid glycine betaine type colloid nano particles are utilized, so that the water permeability, the stain resistance and the stability of the polyamide film are improved. Thus, the prepared modified polyamide reverse osmosis membrane made of the carboxylic acid glycine betaine type colloid nano particles has the high salt reject rate, high water permeation flux and strong stain resistance, the membrane manufacturing is simple and is easy to operate, the cost is low, and the modified polyamide reverse osmosis membrane has the good industrialized application prospect. |
