This study aimed at investigating the influence of the “reaction time” and the “fiber/acid ratio” on the properties of nanocrystalline cellulose isolated from corn husk , which was chosen because it is abundant
and so far it has not been extensively investigated as a raw-material option to produce nanocrystalline cellulose. The results showed that corn husk can be used to produce nanocrystalline cellulose and also that reaction time affected the crystallinity index , particle size and thermal stability of the products. Additionally, an interaction between the reaction time and fiber/acid ratio on the crystallinity degree was observed.When dried by as pray-drying technique , the nanocrystalline cellulose aqueous dispersion produced agglomerates of particles with spherical and irregular shapes.
