Publication date 1995-10 ISSN 0013-4686 1873-3859 Keyword(s) NMR pasticizer polymer electrolytes polyether LiClO4 Summary The addition of low molecular weight solvents such as dimethyl formamide (DMF) and propylene carbonate (PC) to urethane crosslinked polyethers results in enhancement of polymer segmental motion, as determined in this work from polymer 13C spin lattice relaxation measurements (T1) and glass transition temperatures. The formation of salt-polyether complexes results in a decrease in T1, even in the presence of the plasticizer, indicating that the polymer ether molecules are still involved in the alkali metal coordination. In a polymer electrolyte containing 1 mol kg−1 LiClO4 the addition of DMF and PC have significantly different affects on the polymer mobility, although they both enhance the conductivity. The conductivity enhancement therefore is not solely the result of an increased solvent mobility.
