| titleOfInvention | A kind of preparation method of polyethersulfone porous membrane |
| abstract | The invention relates to a preparation process of a porous membrane, in particular to a preparation method of a polyethersulfone porous membrane material. A preparation method of a polyethersulfone porous membrane, the method includes the following steps: 1) adding glucose powder into an organic solvent, stirring until it is completely dissolved, then adding polyethersulfone, stirring at 50-70 ° C until it is completely dissolved, Stand for defoaming to obtain a polyethersulfone film casting liquid; 2) Spread the obtained polyethersulfone film casting liquid on a glass plate with a scraper, place it at a temperature of 20-30°C and a relative humidity of 55-95%, and wait until the organic When the solvent is completely volatilized, a film is formed; the mass fraction of the above-mentioned glucose in the polyethersulfone is 10-30%. The pore size distribution of the polyethersulfone porous membrane prepared by the invention is uniform, the pore size can be adjusted by adjusting the ratio of glucose and polyethersulfone, and the pores in the membrane have good connectivity and large porosity. The method is simple to operate, does not require special equipment, is cheap in raw materials, and is non-toxic and non-polluting. |
