Abstract:
A process for preparing polymetafluoroethylene grafted polystyrene sulfonate proton exchange as membrane includes such steps as dissolving the polymetafluoroethyene in methylpyrrolidone, heating, reflux, adding trigger, adding trichloromethane until the unsoluble solid is fully deposited, taking the solid out, washing, baking, dissolving in methypyrrolidone, pouring on glass plate, baking and sulfonation. It has high electric conductivity of protons.
