Title:
PAPER-CONTAINING STRUCTURE, AND METHOD FOR PRODUCING PAPER-CONTAINING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2024/084882
Kind Code:
A1
Abstract:
In this paper-containing structure, a paper-containing sheet (2) has a first surface (1a) and a second surface (1b), in which a first hydroxyl-group-rich region (11) is formed in the first surface (1a), and a second hydroxyl-group-rich region (14) is formed in the second surface (1b). In each of the hydroxyl-group-rich regions (11, 14), a tensile stress is generated and is balanced with an anti-deformation force of the paper-containing sheet (2) to form a first stable state, thereby keeping a first shape. When the paper-containing structure (1) has a second shape, the forces are balanced with each other to form a second stable state, thereby keeping the second shape. The shape of the paper-containing structure (1) is switched between the first shape and the second shape in at least one direction upon the application of a trigger force.
