▎ 摘　　要

NOVELTY - An ionized graphene oxide-doped anionic film comprises anionic polymer as main chain and fatty guanidino graphene oxide as ionizing agent, where the anionic polymer is polysulfone, polyphenylene ether or polyetheretherketone and the main chain and ionizing agent are ultrasonically mixed to obtain finished product. USE - Ionized graphene oxide-doped anionic film for use in alkaline fuel cells. ADVANTAGE - The ionized graphene oxide-doped anionic film has high stability and better chemical stability under alkaline environment, diffuses distribution of positive charges with resonance effect, avoids degradation of polymer main chain by promotion of ionic groups at surface of graphene oxide and induces graphene oxide to improve mechanical strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for producing an ionized graphene oxide-doped anionic film, which involves preparing guanidine salt by dissolving tetramethylurea in solvent A, dropping oxalyl chloride to the obtained mixture, reacting the mixture at 60 degrees C for 1-10 hours and removing solvent A to obtain guanidine salt in the form of white or light yellow solid powder, preparing silane-guanidine reagent by adding prepared guanidine salt solution to silane reagent, stirring the mixture at more temperature to complete dissolution of guanidine and increasing temperature to 80 degrees C for 24-48 hours to obtain silane-guanidine reagent in the form of brown viscous liquid, preparing fatty guanidino graphene oxide by dissolving 0.5 g graphene oxide solution in 300 ml anhydrous ethyl alcohol, stirring the mixture ultrasonically to obtain uniform dispersion, adding 5-10 ml silane guanidine reagent to the dispersion, reacting the dispersion at room temperature for 24-48 hours to obtain mixed brown liquid, centrifuging the mixed brown liquid, washing precipitate with detergent and freeze-drying the precipitate to obtain solid fatty guanidino graphene oxide, dissolving 0.45 g solid fatty guanidino graphene oxide in 300 ml anhydrous ethyl alcohol, dropping 5-10 ml brominated n-butane to the mixture, reacting the mixture at 80 degrees C for 8-12 hours, cooling the mixture to room temperature, centrifuging the mixture, washing precipitate with detergent, freeze-drying the precipitate to obtain ionized fatty guanidino graphene oxide powder, adding polymer to organic solvent, dissolving the ionized fatty guanidino graphene oxide in polymer-organic solvent mixture, stirring the mixture under warm conditions, processing the mixture ultrasonically to obtain uniform dispersion, paving the uniform dispersion on a glass plate at 50-80 degrees C for 12 hours, peeling off film from the glass plate, immersing the film in alkali solution, washing the film to remove iron ions and drying the film to obtain finished product, where volume ratio of tetramethyl urea, solvent A and oxalyl chloride is 1:2-10:1-1.2, molar ratio of the guanidine salt and silane reagent is 1:1.5-2 and weight ratio of ionized fatty guanidino graphene oxide powder and polymer is 1:0.15-0.35.
