Abstract
Disclosed is an ion conductive film containing a composite body between an ion conductive polymer and a nitrogen-containing compound. The nitrogen-containing compound has an immobilized portion to the ion conductive polymer and exhibits an enantiomeric isomer structure when protonated. Alternatively, the nitrogen-containing compound is capable of assuming a chemical structure in which the multiple bond represented by the double bound is moved, with the atoms constituting the molecule not changing their positions.
Claims18
An ion conductive film having a composite body, said composite body comprising:
- an ion conductive polymer;
- and
- a nitrogen-containing compound, having an immobilized portion to said ion conductive polymer,
- wherein the nitrogen-containing compound is selected from the group consisting of guanine, a salt of guanine, guanidine, a salt of guanidine, guanidinobenzimidazole, a salt of guanidobenzimidazole, purine, a salt of purine, diaminopurine, a salt of diaminopurine, diaminotriazole, a salt of diaminotriazole, histamine, a salt of histamine, and combinations thereof.
The ion conductive film according to claim , wherein said ion conductive polymer is a polymer containing at least one of a sulfonic group and a carboxyl group and a fluorine-containing resin skeleton.
