Cellulose is the most abundant renewable natural polymer material.The molecular chain is composed of β-1,4-linked anhydro-D-glucose units in which every unit is corkscrewed 180° with respect to its neighbors, and the repeat segment is frequently taken to be a dimer of glucose. Cellulose is highly crystalline and generally insoluble, due to the intramolecular hydrogen bond networks extending from the O(3’)-H hydroxyl to the O(5) ring oxygen of the next unit across the glycosidic linkage and from the O(2)-H hydroxyl to the O(6’) hydroxyl of the next residue. Researches of hydrogen bonding in cellulose can dissolve dissolutions, processes and applications of cellulose.
