Composites Based on Cellulose and Chitosan

Abstract

Mixtures of cellulose and chitosan have been obtained under shear deformation conditions using different types of equipment. The presence of an intense interaction between chitosan and cellulose has been revealed. On the basis of IR spectroscopy, a conclusion was drawn that there were qualitative changes in the system of hydrogen bonds between cellulose hydroxyl groups and chitosan amino groups, which indicated mixing of polysaccharides on the molecular level. The possibility of obtaining cellulose–chitosan mixtures in the presence of alkali under shear deformation conditions has been demonstrated.
