| titleOfInvention | A kind of zwitterion conducting membrane for liquid flow battery and preparation method thereof |
| abstract | The invention discloses a zwitterionic conductive membrane for a liquid flow battery and a preparation method thereof. First, flexible "bridges" of different lengths are linked on the side of polybenzimidazole with excellent thermal stability and chemical stability, and then flexible "bridges" of different lengths are grafted on the side of polybenzimidazole with excellent thermal stability and chemical stability. Weak base units with different numbers of tertiary amine groups are finally introduced with sultone through nucleophilic ring-opening reaction to introduce amphoteric groups to obtain polymers containing amphoteric groups, which are formed by casting or solution casting methods; preparation The process is simple, environmentally friendly, low in cost, and the degree of grafting is precise and controllable. The prepared zwitterionic conductive membrane is dense, homogeneous, and transparent. The zwitterion conductive membrane can also be used as a diaphragm material for devices such as high temperature proton exchange membrane fuel cells, gas separation, wastewater treatment and supercapacitors, with excellent performance. |
