A kind of high-flux polyamide nanofiltration or reverse osmosis composite membrane and preparation thereof |
| abstract |
The invention discloses a high-flux polyamide nanofiltration or reverse osmosis composite membrane and a preparation method thereof. The preparation method of the high-flux polyamide nanofiltration or reverse osmosis composite membrane comprises the following steps: (1) preparing an aqueous phase solution containing a polyfunctional amine monomer and an oil phase solution containing a polyfunctional amine reactive monomer; ( 2) sequentially applying the aqueous phase monomer solution and the oil phase monomer solution to one or both sides of the surface of the base film to form a polyamide layer through interfacial polymerization; (3) heat treatment. The advantage of the present invention is that a high-flux polyamidoamine nanofiltration or reverse osmosis composite membrane is prepared by adding acid anhydride compounds and auxiliary agents in the oil phase solution, which is easy to enlarge the process and has significant industrial practical application value. |
