Cellulose

In this book structure and properties of nanostructured cellulose have been discussed. Besides an impact of the structural parameters on physicochemical chemical biochemical physical and mechanical properties of nanostructured cellulose materials was described. Cellulose is a widespread renewable natural polymer which is widely used for the manufacturing of diverse materials and products. Being typical nanostructured polymer cellulose contains nano-scale fibrils crystallites paracrystalline and non-crystalline domains as well as nanopores. To characterize the supermolecular structure of cellulose the primary structural parameters - paracrystallinity crystallinity and amorphicity microfibrillar angle as well as parameters of porous structure should be determined. These structural parameters affect various physical physicochemical chemical and biochemical properties of cellulose materials. The equations were proposed that allow calculate various properties of the polymer on the base of determined structural parameters.
