Investigation on the thermal decomposition kinetics for PDADN by TG-FTIR

Ming Wang

Abstract

The whole process of the PDADN thermal decomposition was investigated by using the DSC-TG-FTIR technology.The thermo-infrared(TIR)curves of the change of the IR characteristics relative absorption intensity of decomposition gas products with temperature and time were obtained.The non-isothermal kinetics treat method for TIR curves was established.The kinetic parameters and mechanism functions of PDADN decomposition gas products were obtained by using the Coats-Redfern and Ozawa equations.The mechanism of PDADN thermal decomposition was analyzed based on iso-kinetic point of the formation rate among all the decomposition gas products.
