| titleOfInvention | Preparation method of novel composite proton exchange membrane material |
| abstract | The invention discloses a preparation method of a novel composite proton exchange membrane material, which sequentially comprises the following steps: a) a sulfonated polyphenyl ether preparation step; b) preparing chloromethylation sulfonated polyphenyl ether; c) preparing azido sulfonated polyphenylene ether; d) 6-tosyl-beta cyclodextrin preparation; e) preparing alkynyl beta-cyclodextrin; f) preparing alkynylated beta cyclodextrin @ graphene oxide; g) and (3) preparing a proton composite membrane material. Compared with the existing SPPO membrane, the proton conductivity at a high temperature of 80 ℃ is improved by 1-1.5 times, the methanol permeability is reduced by more than 150 times, and the stability is also obviously improved; compared with the existing nafion membrane, the methanol permeability is reduced by more than 20 times, and the stability is obviously improved. |
