摘要

A graphene-based laminate including a doped polymer layer is disclosed. The graphene-based laminate may include a substrate; a graphene layer disposed on the substrate and including at least one layer; and a doped polymer layer disposed on at least one surface of the graphene layer and including an organic dopant.

主权项

1. A graphene-based laminate electrode comprising:
a substrate comprising (i) a polymer having a repeating unit that includes at least one selected from the group consisting of a substituted or unsubstituted alkenyl group, a substituted or unsubstituted ester group, a substituted or unsubstituted ether group, a substituted or unsubstituted acrylate group, a substituted or unsubstituted carbonate group, a substituted or unsubstituted styrene group, a substituted or unsubstituted amide group, a substituted or unsubstituted imide group, and a substituted or unsubstituted sulfone group, (ii) a cellulose, or (iii) a mixture thereof; a first doped polymer sheet provided directly above the substrate; a graphene layer provided directly above the first doped polymer sheet and comprising at least one layer; and a second doped polymer sheet provided directly above the graphene layer, wherein the first doped polymer sheet and the second doped polymer sheet comprise an organic dopant, and wherein the organic dopant of the first and second doped polymer sheets is an ionic liquid, and the ionic liquid comprises a compound represented by Formula 1 and/or Formula 2: wherein, in Formula 1, R1 and R2 are identical to or different from each other, and are each independently a hydrogen, a substituted or unsubstituted C1-C16 alkyl group, a substituted or unsubstituted C2-C16 alkenyl group, a substituted or unsubstituted C2-C16 alkynyl group, a substituted or unsubstituted C3-C16 cycloalkyl group, a substituted or unsubstituted C6-C16 aryl group, or a substituted or unsubstituted C6-C20 heteroaryl group; and X− indicates an anion of the ionic liquid, wherein, in Formula 2, R3 and R4 are identical to or different from each other, and are each independently a hydrogen, a substituted or unsubstituted C1-C16 alkyl group, a substituted or unsubstituted C2-C16 alkenyl group, a substituted or unsubstituted C2-C16 alkynyl group, a substituted or unsubstituted C3-C16 cycloalkyl group, a substituted or unsubstituted C6-C16 aryl group, or a substituted or unsubstituted C6-C20 heteroaryl group; and X− indicates an anion of the ionic liquid.
