Title:
METHOD FOR PREPARING HIERARCHICAL WRINKLE STRUCTURE BY USING SACRIFICIAL LAYER, AND HIERARCHICAL WRINKLE STRUCTURE PREPARED THEREBY
Document Type and Number:
WIPO Patent Application WO/2020/096122
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a hierarchical wrinkle structure by using a sacrificial layer, and a hierarchical wrinkle structure prepared thereby. By using a sacrificial layer, the steps of coating a sacrificial layer, generating wrinkles and removing the sacrificial layer are repeatedly performed so as to prepare a hierarchical wrinkle structure, and thus various materials can be used, the number and size of hierarchies in wrinkles can be controlled, and a hierarchical wrinkle structure applicable to a catalyst and in the ultrahydrophobic and omniphobic surface field and the gas sensor field, which require a high surface area, can be prepared.
