NOVELTY - Preparing composite proton exchange membrane material involves preparing sulfonated polyphenylene ether, preparing chloromethylated sulfonated polyphenylene ether, preparing azidosulfonated polyphenylene ether, preparing 6-p-toluenesulfonyl- beta cyclodextrin, preparing alkynylated beta cyclodextrin, preparing alkynyl beta -cyclodextrin@graphene oxide, and preparing proton composite membrane material. USE - Method for preparing composite proton exchange membrane material. ADVANTAGE - The method increases proton conductivity by 1-1.5 times at a high temperature of 80 degrees, the methanol permeability is reduced by more than 150 times, and the stability is improved, methanol permeability is reduced by more than 20 times, and the stability is also significantly improved.
