| titleOfInvention | Polyamide composite nanofiltration membrane and preparation method thereof |
| abstract | The invention relates to a polyamide composite nanofiltration membrane and a preparation method thereof. The preparation method of the polyamide composite nanofiltration membrane comprises the following steps: dissolving polysulfone and a pore-forming agent in a first organic solvent to obtain a polysulfone membrane casting solution; forming a membrane from the polysulfone membrane casting solution by a solid-liquid phase conversion method to prepare a polysulfone porous membrane; sequentially dipping the polysulfone porous membrane into a first medium and a second medium to obtain an interfacial polymerization product, wherein the first medium and the second medium are respectively a water phase solution or an oil phase solution, and the first medium and the second medium are different; the water phase solution comprises a water phase monomer, an acid binding agent and a water phase additive, and the oil phase solution comprises an oil phase monomer. The preparation method of the polyamide composite nanofiltration membrane is simple and feasible, the used raw materials are easy to obtain, the performance is stable, the price is low, the raw materials are easy to obtain, and the polyamide composite nanofiltration membrane is suitable for mass production. |
