Title:
CELLULOSE NANOFIBER LIQUID DISPERSION, CELLULOSE NANOFIBER COMPOSITE RESIN, AND METHODS FOR PRODUCING DISPERSION AND RESIN
Document Type and Number:
WIPO Patent Application WO/2019/045076
Kind Code:
A1
Abstract:
Provided are: a cellulose nanofiber liquid dispersion containing 0.01-30 wt% of a chemically-modified cellulose, 0.01-20 wt% of a surfactant, and 50-99.8 wt% of a dispersion solvent, wherein the chemically-modified cellulose is a fine powder which has undergone half-esterification to modify a hydroxy group contained in the cellulose with a dibasic acid anhydride, and the surfactant is at least one selected from surfactants that have a surface tension of 70 m·N/m or less as measured by the Wilhelmy method, and that result in a contact angle of 90° or less between droplet and solid surface; a cellulose nanofiber composite resin; and production methods for the cellulose nanofiber liquid dispersion and the cellulose nanofiber composite resin.
