Mechanically Initiated Gelation in Solutions of Chitosan with Low Degree of Deacetylation

摘要

Mechanical activation of solutions of chitosan with low degree of deacetylation under the conditions of combined action of ultrasound and high shear stresses in a rotary pulse apparatus leads to the formation of physical hydrogels. Films capable to retain at repeated swelling up to 5000 water without dissolution were prepared by drying of the hydrogels.
