| titleOfInvention | A kind of layer-by-layer self-assembled host-guest recognition PVDF antibacterial nanofiltration membrane and preparation method |
| abstract | The invention discloses a layer-by-layer self-assembly host-guest recognition PVDF antibacterial nanofiltration membrane and a preparation method, comprising the following steps: dissolving a carboxyl group-containing polymer, a polyvinylidene fluoride polymer and a pore-forming agent in a polar solvent , heating and stirring to obtain the casting liquid; scraping the casting liquid on the non-woven fabric and immersing it in the coagulation bath to obtain the base film; immersing the base film in the carboxyl activation solution; adding the polycation solution to continue soaking and taking out; The anion solution is taken out; methyl anthranilate is dissolved in an ethanol aqueous solution, and sprayed onto the membrane to obtain a PVDF antibacterial nanofiltration membrane. The beneficial effects of the present invention are: the carboxyl group on the surface of the base membrane forms a covalent bond with the polycation, and at the same time the electrostatic interaction between the electrolytes and the recognition of the host and the guest improve the stability between the coating layers, and the prepared nanofiltration membrane The skin layer is thin, the flux is high and the hydrophilicity is good; methyl anthranilate is introduced between the separation layers, so that the prepared nanofiltration membrane has antibacterial function. |
