| titleOfInvention | Porous composite membrane for air purification and preparation method thereof |
| abstract | The invention provides a porous composite membrane for air purification and a preparation method thereof, wherein the preparation method comprises the steps of mixing polyvinyl chloride and a first solvent, putting the mixture into a reaction kettle, heating to 55-65 ℃, keeping the temperature and stirring for 2-3h to obtain a membrane forming solution, mixing and stirring polyoxometallate and a second solvent uniformly to obtain an atmosphere solution, blowing steam of the atmosphere solution to the surface of a base membrane by taking nitrogen as carrier gas, simultaneously uniformly coating the membrane forming solution on the surface of the base membrane, and drying the solvent to obtain the porous composite membrane. The porous composite membrane prepared by the method can inhibit microorganisms in the air, prevent the microorganisms from continuously propagating on the surface of the membrane and generate harmful substances to influence the air quality, thereby improving the air purification effect. |
