  • Cellulose II nanocrystal particles and preparation method and use thereof
    Patent number: 11149095
    Abstract: Cellulose II nanocrystal particles have a crystallinity ?80%, a number-average molecular weight ranging from 1200 to 2500, and a molecular weight distribution coefficient Mw/Mn?1.30. The cellulose II nanocrystal particles can be prepared by: subjecting a cellulose raw material to an amorphization reconstitution and then to a crystallization acidolysis. The crystallization acidolysis may be carried out under a low concentration acidic condition. The method enables high efficient and clean production and quality control of cellulose nanocrystal materials.
    Type: Grant
