| Abstract |
Multilayered polyelectrolyte membranes were prepared by layer by layer (LbL) self-assembly method. Recently Nafion film is often adopted as membrane for direct methanol fuel cell (DMFC) because of its high thermal stability and proton conductivity, but it also has high methanol permeability which causes decrease of fuel efficiency of DMFC. In this study, polycation(amPSyn) and polyanion(sPSaz) polymers were synthesized and alternately deposited on Nafion substrate to lower methanol permeability of the membrane. Also, to increase the chemical and mechanical stability of the membrane, each polyelectrolyte layer was cross-linked by click reaction. By this method we expect to improve selectivity(proton conductivity/methanol permeability) of the DMFC membrane. |
