Kinetic Analysis of Thermal Decomposition of Epoxy Resin/Polyaniline Nanocomposites
Polyaniline(PANI) nanofibers were firstly prepared by rapid mixture method, EP/PANI nanocomposite was obtained by in-situ adding the PANI nanofibers to epoxy resin(EP). Thermal degradation behavior of PANI and kinetic analysis of thermal decomposition of EP/PANI nanocomposites were investigated in detail by using thermogravimetric analyser (TGA) in inert atmosphere. Typical three step decomposition profiles of PANI were obtained. On the basis of isoconversional analysis by the methods of Kissinger-Akahira-Sunose method(KAS method) and Flynn-Wall-Ozawa method(FWO method), it was found that the value of the activation energy of EP/PANI nanocomposites is higher than that of pure EP, which proves that PANI nanofibers obviously improve the thermal stability of pure EP.
