Document Type and Number:
WIPO Patent Application WO/2024/071075
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a cellulose nanofiber which can suppress the onset of viscosity and, when applied to film-forming uses such as coatings and films, which can achieve excellent physical properties. Provided is a cellulose nanofiber that satisfies: (A) the carboxyl group content is in the range of 0.8-1.10 mmol/g relative to the absolute dry mass of the cellulose nanofiber; and (B) the aspect ratio is 20 or more but less than 50.
