Claim 8:
9. A polymer electrolyte comprising:
A method of preparing a polymer electrolyte, the method comprising:
preparing a polymer matrix comprising a polymer having a repeating unit represented by the formula, , and
mixing an ionic liquid with the polymer matrix;
wherein R1 to R3 are each independently selected from the group consisting of a substituted or unsubstituted C1-C12 alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heteroaryl group, and combinations thereof;
wherein each R4 is independently selected from the group consisting of hydrogen, a halogen group, a nitrile group, a nitro group, an amine group, a substituted or unsubstituted C1-C10 alkyl group, a substituted or unsubstituted C1-C10 alkoxy group, a substituted or unsubstituted aryl group, a substituted or unsubstituted C5-C14 heteroaryl group, and combinations thereof;
wherein substituents of R1 to R4 are each independently selected from the group consisting of a halogen group, a cyano group, a nitro group, a C1-C8 alkyl group, and combinations thereof;
wherein x is an integer of 1 to 8;
wherein n is an integer of 60 to 3200;
wherein the polymer electrolyte comprises:
