| titleOfInvention | Polymer pervaporation membrane prepared by dialysis method after membrane formation and preparation method of polymer pervaporation membrane |
| abstract | The invention provides a polymer pervaporation membrane prepared by a dialysis method after membrane formation, and a preparation method of the polymer pervaporation membrane. The preparation method comprises the steps of (1) hydroxylating a support body, (2) mixing a polymer and a micromolecule at a mass ratio of 7:3-20:1, (3) adding a crosslinking agent and a catalyst to form membrane casting liquid, and (4) coating a support basement membrane with the membrane casting liquid, then soaking in a dialysate to dialyze the micromolecule, and obtaining the polymer pervaporation membrane. According to the polymer pervaporation membrane and the method, since a micromolecular substance, such as sodium dodecyl sulfate, has the characteristic that the micromolecular substance can be mixed with a polymer solution to form the membrane and leave the membrane by dialysis after membrane forming, after the micromolecular substance is mixed with the polymer, the micromolecular substance is uniformly dispersed in a prepared pervaporation mother membrane, and then a membrane body is dialyzed by the dialysate, so that the micro internal structure and micro surface wettability of the pervaporation membrane are changed, and the permeation flux of the polymer pervaporation membrane is increased. |
