中文摘要 | a novel sulfonated diamine monomer, 4,6-bis(4-aminophenoxy)-naphthalene-2-sulfonic acid(bapns), was synthesized. a series of sulfonated polyimide copolymers was prepared from bapns, 1,4,5,8-naphthalenetetra-carboxylic dianhydride(ntda) and nonsulfonated diamine 4,4'-diaminodiphenyl ether(oda). flexible, transparent, and mechanically strong membranes were obtained. the novel sulfonated polyimide(spi) membranes show higher conductivity, for example, spi-100 shows a conductivity of 0.0698 s/cm at 80 a degrees c(spi-x: x refers to molar fraction of bapns). the membranes exhibit the permeability of methanol from 2.18x10(-7) cm(2)/s to 2.57x10(-7) cm(2)/s, which is much lower than that of nafion(2.00x10(-6) cm(2)/s). the copolymers were thermally stable up to 330 a degrees c. the sulfonated polyimide copolymers also show reasonable mechanical strength; for example, the maximum tensile strength at break of the sulfonated polyimide copolymer with 100%(molar fraction) bapns is 1.35 gpa under high moisture conditions. the optimum concentration of bapns was found to be 100%(molar fraction) from the view point of proton conductivity, methanol permeability, and membrane stability. |
