1. A method of transferring graphene, the method comprising the steps of:
forming a graphene on a first substrate;
forming a polymer precursor mixture on a second substrate;
disposing the graphene oppositely to the second substrate having the polymer precursor mixture formed thereon;
pressing the first substrate and the second substrate while curing the polymer precursor mixture; and
peeling off the first substrate,
wherein the polymer precursor mixture contains:
a dopant material comprising an amine group-containing polymer or a precursor thereof; and
a curing agent selected from the group consisting of glutaraldehyde, propylene dialdehyde, butyl dialdehyde, succinaldehyade, pentane-2,4-dione, acetylacetone, acetonylacetone, and combinations thereof.
