Abstract
Functionalized organic/inorganic composite anion exchange membranes (AEMs) were prepared with quaternized cardo-poly(etherketone) (QPEK-C) and N-(trimethoxysilylpropyl)-N,N,N-trimethylammonium chloride (TMSP-TMA+Cl?). With an optimized loading of 20wt% of TMSP-TMA+, the sulfate ion conductivity and VO2+ permeability of the composite membrane were 8.4
