Method for improving graphene property, method for manufacturing graphene using the same, graphene manufactured by the same

摘要

PURPOSE: A method for improving graphene characteristic based on laser, a method for manufacturing graphene using the method, graphene manufactured by the method are provided to obtain graphene at low temperatures and to obtain flexible graphene elements. CONSTITUTION: Graphene grown on a substrate(101) is thermally treated by irradiating laser beam. The graphene is grown at low temperatures of 400 degrees Celsius or less. The substrate is a plastic substrate. A method for manufacturing the graphene includes the following: the laser beam is moved; a plurality of times of thermal treatment is implemented toward whole graphene region; graphene structures are re-aligned in planar hexagonal structures.
