Abstract
A method for manufacturing graphene having a wrinkle pattern is provided. The method includes forming a wrinkle providing layer having a first thermal expansion coefficient on one surface of a graphene layer, forming a substrate having a second thermal expansion coefficient on one surface of the wrinkle providing layer, and performing a heat treatment to form wrinkles on the wrinkle providing layer by a difference between the first and second thermal expansion coefficients, thereby forming wrinkle patterns on the graphene layer.
