Title:
STRUCTURE HAVING EXCELLENT GRIPPING FORCE AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2021/157933
Kind Code:
A1
Abstract:
The present invention relates to a structure having excellent gripping force and a method for producing the same, wherein the structure comprises: a substrate; a patterned polymer layer formed on one surface of the substrate; an adhesive layer filled between patterns of the patterned polymer layer; and an amphoteric polymer film that is formed on the surface of the patterned polymer layer and is capable of forming reversible wrinkles upon contact with water. As the amphoteric polymer film is laminated on the surface of the patterned polymer layer, the structure according to the present invention maintains a flat surface under dry conditions and forms wrinkles under wet conditions in which moisture derived from organic compounds having hydroxy groups such as water, methanol, and ethanol is present, such that the structure exhibits excellent gripping force in both dry and wet conditions.
