Semi-IPN system electrolyte membranes composed of sulfonated poly(arylene ether ketone) block copolymer and organosiloxane based hybrid network for fuel cell |
| 초록 |
A semi-interpenetrating polymer network (semi-IPN) proton exchange membrane is prepared from the sulfonated poly(arylene ether ketone) block copolymer and organosiloxane-based organic/inorganic hybrid network. The organosiloxane network is synthesized from 3-glycidyloxypropyltrimethoxysiane and 1-hydroxyethane-1,1-diphosphonic acid. The methanol permeability is much lower than Nafion® 117 under addition of the organosiloxane network. The proton conductivity is increases with an increase the organosiloxane network content; the membrane containing the 20-24 wt% organosiloxane network shows higher conductivity than Nafion® 117 . Chemical synthesis of the semi-IPN membranes is identified using FTIR and thermal stability was analyzed by the thermal gravimetric (TGA) method. The water uptake, ion exchange capacity (IEC), oxidative stability and mechanical properties of the semi-IPN membrane were investigated for their applications in proton exchange membrane fuel cells. |
