IR Spectral Study and X-Ray Structural Analysis of the Supramolecular Structure of Cellulose Powder

IR spectroscopy and x-ray structural analysis were used to study the supramolecular structure of cellulose powders obtained by the hydrolytic decomposition of bleached coniferous cellulose using mineral acids and its mercerized form. IR spectroscopy was used to establish the nature of the intermolecular bonds in the cellulose powder macromolecules. The Rietveld refinement was used to determine crystallinity and size of coherent scattering regions as well as to calculate the lattice periods of the crystalline component of these materials.
