Study of cellulose-chitosan composites. Solid-phase modification, rheology, films

ABSTRACT

A method is proposed for processing of experimental data which would allow adequately describing the rheological behavior of systems whose disperse phase contains swelling particles of anisometric shape. Polysaccharide films with a high degree of swelling were obtained from dispersions of powdered cellulose in chitosan solutions. The high sorption capacity of the films, good adhesion to skin, lack of toxicity, and possibility of immobilizing drugs in them allow considering these films as promising materials for healing wounds and burns.
