METHOD FOR PRODUCING LAYERED PRODUCT CONTAINING CELLULOSE NANOFIBERS
Document Type and Number:
WIPO Patent Application WO/2023/100924
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a method for producing a layered product having a functional layer that is ideal for use in a variety of industrial applications. The present invention provides a method for producing a layered product, the method including a layering step for forming a functional layer containing anionically modified cellulose nanofibers on a supporting substrate using a coating method such as a pre-metering coating method, a post-metering coating method, or a transfer coating method. The anionically modified cellulose nanofibers are oxidized cellulose nanofibers having a carboxyl group and/or a carboxylate group, and are preferably carboxyalkylated cellulose nanofibers, phosphoric acid esterified cellulose nanofibers, or sulfuric acid esterified cellulose nanofibers.
