| 摘要 |
An ionically conducting solid polymer electrolyte comprises a non-aqueous complex of plasticized polyacrylamide or a plasticized poly(N-monosubstituted acrylamide) or a plasticized copolymerised acrylamide or plasticized copolymerised poly(N-monosubstituted acrylamide> <IMAGE> with a monovalent alkali metal salt, where R is hydrogen, or is alkyl, alkenyl, cycloalkyl, cycloalkylene or aryl (all of which may be optionally substituted). The alkali metal salts are preferably perchlorates, perfluorinated carboxylates or trifluoromethanesulphonates. In the examples, the acrylamide monomers are polymerized in the presence of the alkali metal salts. Use: as solid ionic electrolytes in galvanic cells and electrochromic displays. |
