Amendment in electrical and thermal properties of bismuth telluride with dispersion into conducting polymers nanocomposites
摘要
Nanofiller dispersions into polymer nanocomposites aid in enhancing their electronic and thermal properties. In the present work we have dispersed Bismuth Telluride (Bi2Te3) nanofiller into conducting polymers Polyaniline (PANI) and Polypyrole (PPY) using electroplating method to form Bi2Te3-polymer nanocomposites and found amended electrical and thermal properties. Bi2Te3 and its respective nanocomposites were structurally characterized using X-Ray Diffraction and Transmission Electron Microscopy. The successful dispersion of Bi2Te3 into polymer nanocomposites has been confirmed using Transmission electron Microscopy and spectroscopically utilizing Fourier Transform Infrared Spectroscopy and UV-Vis spectroscopy. More amendment in electrical properties of Bi2Te3 has been observed with integration of Polyaniline with better thermal stability with incorporation of Polypyrrole polymer. Therefore, integration of Bi2Te3 into Polyaniline and Polypyrrole nanocomposites would result in better thermoelectric device under ambient conditions.
