中文摘要	in order to enhance the ion exchange capacity (iec) in the proton exchange membrane materials, a novel sulfonated poly(arylene ether ketone) (sqnpaek) containing tri-side chains in one unit is synthesized by direct polymerization. the sqnpaek membrane shows excellent proton conductivity up to 0.102s cm(-1) at 80 degrees c, which are superior to previous side-chain-type and main-chain-type sulfonated polymer membranes at similar iec. cross-linked membranes are then obtained by a heating reaction at 190 degrees c, using 4,4'-diglycidyl (3,3',5,5'-tetramethylbiphenyl) epoxy resin (tmbp) as the cross-linker. as expected, the water uptake and the methanol permeability of the cross-linked membranes decrease with increasing the content of tmbp. compared to nation 117, the cross-linked membranes show comparable proton conductivities and much higher selectivities, which are in the range of 5.18 x 10(5)-1.46 x 10(6) s s(-1) cm(3). other properties of the cross-linked membranes, such as mechanical properties, thermal properties, are also investigated. all the results indicated that the cross-linked membranes based on sqnpaeks and tmbp are promising candidate for direct methanol fuel cells.
