| titleOfInvention | Method for preparing amphoteric ionic membrane based on amphoteric polysilicone copolymer |
| abstract | Firstly, selecting a monomer A containing double bonds and halomethyl, a monomer B containing carboxyl, anhydride or sulfonic acid groups and a monomer C containing double bonds and alkoxy silicon groups, mixing the three monomers with a solvent and an initiator, then carrying out free radical copolymerization reaction, and carrying out rotary evaporation concentration to obtain the multi-silicon copolymer solution. The poly-silicon copolymer can be subjected to the following two ammonification modes, one mode is firstly ammonification and then blending with polyvinyl alcohol (PVA), namely, the poly-silicon copolymer solution is dripped into trimethylamine organic solution, then the poly-silicon copolymer solution and the PVA are subjected to sol-gel reaction, and a zwitterion membrane is formed after heat treatment; the other mode is that the polymer is firstly blended with PVA to form a film and then is aminated, namely, the polysilicone copolymer solution is directly dripped into the PVA solution to form a membrane after sol-gel reaction and heat treatment, and the membrane can be selectively soaked in trimethylamine aqueous solution for quaternization to obtain the zwitterion film. |
