Cellulose nanocrystal ball

Excellent re-dispersibility in water and high activity due to no surface treat

Overview

Cellulose nanofiber (CNF) and cellulose nanocrystal (CNC), which are lighter and stronger than steel, are expected as a filler to replace an inorganic material. Although CNC with a lower aspect ratio and higher crystallinity than CNF is more suitable as a filler, research and development for commercialization has not progressed. This technology relates to a method for simply and easily producing CNC ball by homogenizing microcrystalline cellulose in a good solvent and replacing good solvent to poor solvent. The CNC ball obtained by this method is excellent redispersibility in water, and the surface modification for use as a filler can be easily.
