Polypyrrole thin films were prepared by solvent evaporation method. The thermal analysis (TG/DTG) was carried out on NETZSCH - Geratebau GmbH Thermal Analyser (Model - STA 409 C), at RSIC, Chennai. The conducting polypyrrole thin film samples S1, S5, S8, S10, S12, S15 and S20 in powder form were used. The weights of sample were 19.660; 22.570; 20.460; 20.640; 21.190; 22.670 and 20.650, respectively. The temperature range was 30 to 500ºC with heating rate of 10 K/min. The atmosphere used was nitrogen. TG curves of 1, 5, 8,10,12,15 and 20 wt % of pyrrole thin films which are scanned in the temperature 293 to 1173 K. The data obtained from TG and DTG curves.
