Preparing method of redispersible cellulose nanofiber， redispersible cellulose nanofiber therefrom， and dispersion method of redispersible cellulose nanofiber

The present invention (1) preparing a cellulose-based material; (2) oxidizing the cellulose-based material in an aqueous solution; (3) preparing a suspension with the resulting cellulose oxide and treating it with alkali; And (4) dispersing the resulting suspension with a high pressure homogenizer to prepare a dispersion; provides a method for producing a redispersible cellulose nanofiber comprising a. Therefore， the present invention can effectively manufacture cellulose nanofibers that are easily redispersed by reducing the energy of high-pressure dispersion， which is post-treatment， by simply adjusting the pH of the cellulose nanofibers that are produced by oxidation treatment and preventing hydrogen bonds generated during drying. .
