| 中文摘要 | sulfonated poly(arylene ether ketone) bearing carboxyl groups (spaek-c) membranes were first modified by alternating deposition of oppositely charged polyaniline (pan!) and phosphotungstic acid (pwa) via the layer-by-layer method in order to prevent the crossover of methanol in a direct methanol fuel cell. the methanol permeability of spaek-c (pani/pwa)(s) is 2 orders of magnitude less than those of nafion 117 and pristine spaek-c. furthermore, the modified membrane shows a proton conductivity of 0.093 scm(-1) at 25 degrees c and 0.24 scm(-1) at 80 degrees c, which are superior to those of nafion 117 and pristine spaek-c. fourier transform infrared spectroscopy confirms that pan! and pwa are assembled in the multilayers. the sem images show the presence of thin pani/pwa layers coated on the spaek-c membrane. thermal stability, water uptake, water swelling, proton and electron conductivity at different temperature of the spaek-c and spaek-c-(pani/pwa)(n) membranes are also investigated.
