NOVELTY - Preparing graphene modified sulfonated polyphenylene oxide proton film comprises e.g. sulfonating using chlorosulfonic acid as sulfonating agent, and modifying polyphenylene ether, carrying out doping modification of graphene oxide using 1H-1,2,3-triazole as doping modifier, dissolving graphene-tri-tert-butylphosphine in dimethylformamide to obtain graphene-tri-tert-butylphosphine/dimethylformamide solution having a concentration of 8-12 mg/ml, ultrasonically dispersing for 25-30 minutes, dissolving sulfonated polyphenylene ether in dimethylformamide to obtain polyphenylene ether/dimethylformamide solution having a concentration of 46-50 mg/ml and ultrasonically dispersing for 25-30 minutes, where volume ratio between graphene-tri-tert-butylphosphine/dimethylformamide solution, polyphenylene ether/dimethylformamide solution, graphene-tri-tert-butylphosphine/dimethylformamide solution and polyphenylene ether/dimethylformamide solution is 1:5-7 and ultrasonicating for 1-2 hours. USE - The method is useful for preparing graphene modified sulfonated polyphenylene oxide proton film. ADVANTAGE - The film: improve proton migration and continuous proton defect. DETAILED DESCRIPTION - Preparing graphene modified sulfonated polyphenylene oxide proton film comprises (i) sulfonating using chlorosulfonic acid as sulfonating agent, and modifying polyphenylene ether, (ii) carrying out doping modification of graphene oxide using 1H-1,2,3-triazole as doping modifier, (iii) dissolving graphene-tri-tert-butylphosphine in dimethylformamide to obtain graphene-tri-tert-butylphosphine/dimethylformamide solution having a concentration of 8-12 mg/ml, ultrasonically dispersing for 25-30 minutes, dissolving sulfonated polyphenylene ether in dimethylformamide to obtain polyphenylene ether/dimethylformamide solution having a concentration of 46-50 mg/ml and ultrasonically dispersing for 25-30 minutes, where volume ratio between graphene-tri-tert-butylphosphine/dimethylformamide solution, polyphenylene ether/dimethylformamide solution, graphene-tri-tert-butylphosphine/dimethylformamide solution and polyphenylene ether/dimethylformamide solution is 1:5-7, ultrasonicating for 1-2 hours, pouring into the petri dish, placing in a vacuum oven at 70-85 degrees C for 20-30 hours, place in a constant temperature oven at 95-105 degrees C for 1-2 hours, removing the film and measure its film thickness, adding membrane into 1.8-2 mol/l sulfuric acid solution, soaking in a water bath at 60-65 degrees C for 4-5 hours, removing film, washing the residual acid on the film surface with deionized water, placing in a blower at 58-60 degrees C for 1-3 hours and then drying film.
