Molecular Complexes of Cellulose with Metals New Development
The existence of periodical substructures in cellulose has been shown in many papers1’4. In order to confirm this, various chemical methods were applied. In combination with advanced experimental physical procedures, particularly with electron microscopy, these methods give visualization of structural elements. Accorging to some researches, these periodical structures are formed by aggregates of cellulose molecules 30-40 A in width and with the length depending on the degree of polymerization of the sample. The mode of torsion of the macromolecules, i.e. the mode of steric arrangement of the macromolecules with respect to each other, is of importance and can vary. This determines distinction in cellulose hydrogen bonding system and, hence, its reactivity.
