The possibility of obtaining nanocellulose from organosolv pulp from kenaf fibers by hydrolysis with sulfuric acid of a lower concentration (43%) compared with the traditional conditions (60%-65%) is demonstrated. The structure and properties of the nanocellulose were studied by SEM, FT-IR, XRD, TEM, AFM, and TGA. It was found that the product has a degree of crystallinity of up to 80%, and forms a porous network of particles with diameters of 10-28 nm. The nanocellulose films have a density of 1.39 g/cm3, transparency of up to 76%, and tensile strength of 40 MPa.
