Abstract
The decomposition kinetics of the pure polyaniline PANI PANI/CeO2 composites and PANI/Dy2O3 composites were investigated using thermogravimetry TG technique under air atmosphere Two isoconversional methods and multiple linear regression method were used for the evaluation of kinetic parameters from the TG data of different heating rates The estimation of activation energy values shows that the addition of CeO2 significantly enhances the thermal stability of PANI matrix while the presence of Dy2O3 slightly reduces the thermal stability of the final composites The kinetic analysis results show that the kinetic model for the decomposition process for PANI is D3 and for the two kinds of composites is F1–D1The authors gratefully acknowledge the National Natural Science Foundation of China under the Grant No 20903017 the Program for Liaoning Excellent Talents in University No LJQ2013051 and the Science and Technology Foundation of Dalian under the Grant No 2010J21DW010 for financial support to this work
