| 中文摘要 | using poly(styrene-co-maleic anhydride) as a backbone and poly(ethylene glycol) methyl ether (pegme) with different molecular weights as side chains, three comb-like polymers and their li salt complexes were synthesized. the dynamic mechanical properties and conductivities were investigated. results showed that the polymer electrolytes possess two glass transitions: alpha -transition and beta -transition, and the temperature dependence of the ionic conductivity shows wlf (williams-landel-ferry) behavior. based on the time-temperature equivalence principle, a master curve was constructed by selecting t-beta as reference temperature. the values of the wlf parameters (c-1 and c-2) were obtained and were found to be almost independent of the length of the pegme side chain and the content of li salt. by reference to t-0 = 50 degreesc. the relation between log tau (c) and c was found to be linear. the master curves are displaced progressively to higher frequencies as the molecular weight of the side chain is increased. the relation between log tau (n) and the molecular weight of the side chain is also linear.
