Study of Characterization of Pure and Malachite Green Doped Samples Using Spectroscopic Studies

摘要

This paper describes the results of SEM, EDX, UV-vis and TSDC study of malachite green doped PVK thermelectrets. TSDC study has been carried out in the temperature range 30 deg C to 150 deg C with four different polarizing fields. One peak was observed at 110 +- 10 deg C which shifts toward high temperature with the increase in polarizing field. The activation energy found by initial rise method are 0.27 +- 0.02 eV for pure and 0.40+-0.03eV for malachite green doped PVK thermoelectrets. Spectroscopic study concluded that impregnation of malachite green in polymer matrix forms charge transfer complexes.
