| titleOfInvention | Polyelectrolyte sandwich magnetically responsive polypiperazinamide composite nanofiltration membrane and preparation method |
| abstract | The invention discloses a polyelectrolyte sandwich magnetically responsive polypiperazine amide composite nanofiltration membrane and a preparation method. Anionic and cationic polyelectrolytes are used to alternately and dynamically assemble layer by layer on the surface of a base membrane to form a polyelectrolyte layer, and the polyelectrolyte layer is covered with a polyelectrolyte layer. A layer of magnetically responsive polypiperazine amide layer is formed on the surface of the membrane by an interfacial polymerization method, and heat treatment is performed to obtain a polyelectrolyte sandwich magnetically responsive polypiperazine amide composite nanofiltration membrane. The invention prepares a multi-separation-layer composite nanofiltration membrane with high flux, high interception and strong anti-pollution performance, and has unique advantages such as abundant hydrophilic functional groups on the membrane surface and nano-sized pores to enhance the comprehensive performance of the nanofiltration membrane. |
