| titleOfInvention | Composite nanofiltration membrane and preparation method thereof |
| abstract | The invention relates to the technical field of separation membranes, and discloses a composite nanofiltration membrane and a preparation method thereof. The composite nanofiltration membrane comprises a base membrane and a coating layer formed on the surface of the base membrane, wherein the coating layer contains a polymer and an additive, and the polymer is a polymer with a structure shown in a formula (2-1) or (2-2) or a polymer with a structure shown in a formula (3-1) or (3-2). The composite nanofiltration membrane has broad-spectrum and long-acting sterilization and antibacterial effects. |
