Polymer electrolytes with exclusively cationic conductivity
The synthesis of exclusively cation conducting polymer electrolytes based on a nylon-1 backbone, ethylene-oxide side chains, and attached dibutyl phenolate anions is described. The tendency for ion pair formation appears to be reduced as the conductivity of the sodium-containing compound reaches /approximately/2 /times/ 10/sup /minus/6/ S-cm/sup /minus/1/ at 50/degree/C. /sup 23/Na nuclear magnetic resonance measurements demonstrate: (1) motional narrowing of the mobile Na/sup +/ resonance above the glass transition temperature; (2) mobile Na/sup +/ concentrations of /approximately/75% at 40/degree/C; and (3) insensitivity of the linewidth to applied hydrostatic pressure up to 2 kbar. Similarities between these findings, and those in ''conventional'' polymer-salt electrolytes are discussed. 14 refs., 5 figs.
