| 英文摘要 | layer-by-layer (lbl) self-assembly is a simple and elegant method of constructing organic-inorganic composite thin films from environmentally benign aqueous solutions. in this paper, we utilize this method to develop proton-exchange membranes for fuel cells. the multilayer film is constructed onto the surface of sulfonated poly(arylene ether ketone) (spaek-cooh) membrane by lbl self-assembly of polycation chitosan (cts) and negatively charged inorganic particle phosphotungstic acid (via). the highly conductive inorganic nanoparticles ensure spaek-cooh-(cts/pta)(n) membranes to maintain high proton conductivity values up to 0.086 s cm(-1) at 25 degrees c and 0.24s cm(-1) at 80 degrees c, which are superior than previous lbl assembled electrolyte systems. these multilayer systems also exhibit extremely low water swelling ratio and methanol permeability. the selectivity of spaek-cooh-(cts/pta)(8) is 2 orders of more than nafion (r) 117, which is attractive in direct methanol fuel cells (dmfcs).
