| titleOfInvention | Preparation method of reverse osmosis membrane containing buffer layer free interface polymerization |
| abstract | The invention discloses a preparation method of a reverse osmosis membrane containing buffer layer free interface polymerization, which is characterized in that a buffer layer is added between a water phase and an organic phase in the reverse osmosis membrane prepared by free interface polymerization to slow down the intensity and heterogeneity of polymerization reaction, so that the reverse osmosis membrane formed by free interface polymerization is uniform and compact, the problems of uneven distribution of reaction monomers and intense local reaction in free interface polymerization are solved, the conditions of wrinkles and accumulation of a dense layer of the reverse osmosis membrane are avoided, the desalting performance and the chlorine resistance of the reverse osmosis membrane are improved, and the effective control of the polymerization reaction at an interface is realized. The method disclosed by the invention is simple to operate and low in cost, and can be used for rapidly preparing the reverse osmosis membrane which is uniform in structure, excellent in desalination performance, good in chlorine resistance and excellent in stability in batches. |
