Zusammenfassung:The invention discloses a preparation method of a novel sulfonated polyetheretherketone/sulfonated graphene oxide composite proton exchange membrane, and relates to the field of composite materials. SGO-C-triple bond-C is prepared; polyetheretherketone is dissilved in concentrated sulfuric acid to prepare sulfonated polyetheretherketone; SPEEK-CH2N3 is prepared through a chloromethylation reactionand an azidation reaction; SPEEK-SGO is prepared by a click chemical reaction of alkyne and azide under the catalysis of CuBr; and the SPEEK-SGO composite membrane is prepared by a solution casting blending phase transformation process in order to achieve the preparation and modification of the sulfonated polyetheretherketone membrane. The composite proton exchange membrane improves the proton conductivity, the coulombic efficiency and the power density of polymer membranes in fuel cells, and can be applied to the field of chemical industry. 本发明公开了种新型磺化聚醚醚酮/磺化氧化石墨烯复合质子交换膜的制备方法,涉及复合材料领域,本发明制备SGO-C≡C;浓硫酸溶解聚醚醚酮制备磺化聚醚醚酮;
