Title:
ANIONICALLY-MODIFIED CELLULOSE NANOFIBER DISPERSION LIQUID AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/131084
Kind Code:
A1
Abstract:
This method for producing an anionically-modified cellulose nanofiber dispersion liquid includes a step for preparing a dispersion liquid containing an anionically-modified cellulose, and a step for defibrating the cellulose in the dispersion liquid, wherein the hydroxy groups of at least a portion of the pyranose rings of the anionically-modified cellulose are modified by an oxidation or substitution reaction, and the anionically-modified cellulose dispersion liquid to be subjected to the defibration has an electrical conductivity of 500 μS/cm or less at a concentration of 1.0 wt%. The dispersion liquid is highly transparent.
