Abstract

An exchange membrane containing modified maleimide oligomers comprising sulfonated poly(aryl ether ketone) (S-PAEK) and modified maleimide oligomers. The exchange membrane uses the modified maleimide oligomers having a hyper-branched architecture as matrix, and introduces them into S-PAEK to constitute semi-interpenetration network (semi-IPN), so as to intensify water holding capacity, chemical resistance, the electrochemical stability and thermal resistance of the ionic/proton exchange membrane. The exchange membrane can be used to fabricate the membrane electrode assemblies, fuel cells, and be applied them to the fields of seawater desalination, heavy water and sewage treatment, and biomass-energy resources.
