| titleOfInvention | Method for preparing antibacterial anti-pollution filter membrane based on charge regulation and control |
| abstract | The invention discloses a method for preparing an antibacterial and anti-pollution filter membrane based on charge regulation. The preparation method mainly comprises the following specific steps: (1) dissolving a polymer material, a negatively charged amphiphilic polymer and a pore-foaming agent in a solvent to obtain a uniform and stable membrane-making solution; (2) carrying out non-solvent induced phase separation on the membrane-making solution obtained in the step (1) to form a negative-charge micropore basement membrane; (3) and (3) placing the negatively charged microporous basement membrane obtained in the step (2) in a positively charged monomer solution, and placing under an ultraviolet lamp for irradiation to obtain the antibacterial and anti-pollution filtering membrane. By regulating and controlling the grafting conditions, when the zeta potential on the surface of the filtering membrane is 0.5-15.0 mV, the filtering membrane has excellent antibacterial and anti-pollution performance. The method has the modification means with simple and convenient operation, lasting effect and controllable surface property. |
