Title:
LAYERED MATERIAL, AND PRODUCTION METHOD AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/018519
Kind Code:
A1
Abstract:
This layered material contains: a first base material; and a sheet material layered on the first base material so as to be integrated therewith. The material of the first base material is selected from the group consisting of biomass material, plastic, metal, ceramics, glass, molded pulp product, and paper. The sheet material is formed substantially from a plant-derived component. The infrared absorption spectrum of the sheet material has an absorption peak in the 1715-1725 cm-1 region. The sheet material is produced by: dissolving a plant raw material in an organic acid to obtain a plant solution; and removing the liquid component of the solution. The layered material is produced by layering and thermocompressing the sheet material and the first base material. A method for modifying the surface of a formed product includes layering the sheet material onto the surface of the formed product and thermocompressing the same. An adhesive includes the plant solution or the sheet material.
