Abstract
Cellulose is the most abundant natural biopolymer. This polysaccharide is widely used in various fields such as pharmaceuticals, medicine, and industry, which is partly due to its high availability, low cost, and exceptional mechanical properties, particularly high Young's modulus. The mechanical and physicochemical properties of cellulose are determined by its supramolecular and morphological structure, specifically the perfection of its amorphous-crystalline state. The relative content of crystalline material in cellulose is described by the crystallinity index (degree of crystallinity). In this work, the crystallinity indices of previously studied cellulose samples and hydrogel derived from powdered cellulose were calculated using the modified Ruland method. The scattering pattern of the latter is atypical and is not fully described by theoretical models.
