Making the cellulose nano- fiber which possesses the basis

摘要

PROBLEM TO BE SOLVED: To provide a method of producing a cellulose nanofiber dispersion liquid suitably used for compounding a cellulose nanofiber into a wide range of organic solvent-soluble polymer materials.;SOLUTION: The method of producing the cellulose nanofiber dispersion liquid includes: a step of dispersing the cellulose nanofiber having a carboxylate-type group into an aqueous solvent to prepare a first cellulose nanofiber dispersion liquid; a step of replacing the carboxylate-type group with a carboxylate amine salt-type group having an organic group; and a step of dispersing the cellulose nanofiber having the carboxylate amine salt-type group into an organic solvent.;COPYRIGHT: (C)2012,JPO&INPIT
