Abstract
The present disclosure relates to a method of transferring a 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.

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,
