| titleOfInvention | Preparation method of monolithic polyaryletherketone bipolar membrane with side chain containing porphyrin water dissociation catalytic group |
| abstract | The invention relates to a preparation method of a monolithic polyaryletherketone bipolar membrane with side chains containing porphyrin water dissociation catalytic groups, which takes bromomethylated polysulfone and bromomethylated polysulfone polymers as raw materials to respectively synthesize polysulfone-based membrane mixed liquor containing porphyrin and epoxy group side groups, the mixed liquor is cast on a clean glass plate after being mixed, and the polysulfone-based membrane containing porphyrin and epoxy group side groups is prepared by drying; and after the base membrane is sulfonated, aminated and quaternized, washing with deionized water to obtain the monolithic polyaryletherketone bipolar membrane containing the phthalocyanine group side group. The bipolar membrane prepared by the invention introduces epoxy groups on the polysulfone side groups through nucleophilic substitution reaction, and introduces anion and cation exchange membranes in polysulfone molecular chains, thereby omitting a film forming process and avoiding the use of carcinogenic chloromethyl ether. The prepared bipolar membrane has an autocatalytic effect, and is low in resistance and transmembrane voltage. The problems that the composite bipolar membrane is easy to bubble and crack at the middle interface layer in the using process can not occur after long-term use. |
