A semi-interpenetrating polymer network (semi-IPN) proton exchange membrane is prepared from the ketone sulfonated poly(arylene ether ketone) block copolymer and organosiloxane-based organic/inorganic hybrid network. The network is synthesized from 3-glycidyloxypropyltrimethoxysiane and 1-hydroxyethane-1,1-diphosphonic acid. The thermal stability of the membrane was analyzed by the thermal gravimetric (TGA) method. The radial structure of the particles and the average ionic cluster dimension of the membrane was analyzed by the small angle X-ray scattering (SAXS) technique. The proton conductivity, water uptake, ion exchange capacity (IEC), methanol permeability, oxidative stability and mechanical properties of the semi-IPN membrane were investigated for their applications in proton exchange membrane fuel cells. |
