Title:
アニオン変性セルロースナノファイバーの製造方法
Document Type and Number:
Japanese Patent JP7239294
Kind Code:
B2
Abstract:
To provide a method for efficiently producing an acid type anion modified-cellulose nanofiber capable of forming a dispersion having high transparency.SOLUTION: A mixture of a metal salt type anion modified-cellulose and an amphipathic polymer compound is mechanically treated to form a metal salt type anion modified-cellulose nanofiber dispersion, an acid and a water-soluble organic solvent are added to the dispersion, and the metal salt type is converted into an acid type.SELECTED DRAWING: None
