Title:
WRINKLE-SMOOTHING UNIT, AND GRAPHENE COMPOSITE STRUCTURE PREPARATION APPARATUS COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2023/095994
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a wrinkle-smoothing unit and a graphene composite structure preparation apparatus comprising same, the unit enabling wrinkles, which occur during preparation of a graphene composite structure, to be smoothed out, and thus enables a graphene composite structure with excellent quality to be prepared. To this end, disclosed are a wrinkle-smoothing unit, and a graphene composite structure preparation apparatus comprising same, the unit comprising: a roller part, which comes in contact with and supports one surface of a moving graphene composite structure, suctions the contacted one surface of the graphene composite structure, and smooths out, by means of suction power, wrinkles present in the graphene composite structure; and a pressure part, which is arranged on the other surface of the graphene composite structure and presses the graphene composite structure toward the roller part.
