Thermal Modification and Study of the Structure of Chitosan Films

Using IR spectroscopy, elemental analysis, and potentiometric titration, it was confirmed that amidation and cross linking of the polymer take place in heat treatment of chitosan films in the S-form. It is shown that these processes also take place in hardening of films from formic acid solutions of...

Description
Summary:Using IR spectroscopy, elemental analysis, and potentiometric titration, it was confirmed that amidation and cross linking of the polymer take place in heat treatment of chitosan films in the S-form. It is shown that these processes also take place in hardening of films from formic acid solutions of chitosan by vaporization of the solvent at high temperature.[PUBLICATION ABSTRACT]
