Thermal Characterizations of Chitosan and Polyacrylonitrile Semi-Interpenetrating Polymer Networks

Abstract

The thermal characterization of the semi-interpenetrating polymer networks (IPNs) was investigated by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and dielectric analysis (DEA). The melting temperature (Tm) of semi-IPNs were observed with increasing chitosan content using DSC. DEA was employed to ascertain the glass transition temperature (Tg) of semi-IPNs. In the results of DEA, three relaxation peaks appeared around 100, 200 and 290 'C for the semi-IPNs, and the semi-IPNs exhibited two Tgs indicating the presence of phase separation in the semi-IPN. The thermal decomposition of semi-IPNs was investigated using TGA and appeared near 208 ⁰C.
