Abstract
The remarkable properties of Polypyrrole (PY) hold immense potential for revolutionizing electronic device technologies. From flexible electronics to high-performance sensors, PY and its nanocomposites offer a plethora of opportunities to engineer advanced electronic components with enhanced functionalities. The properties of Polypyrrole (PY), Cobalt ferrite (CF) and their nanocomposites (PY1, PY2, PY3, PY4) have been explored with increasing amount of Cobalt ferrite. Their synthesis and nano size are confirmed by X-ray diffraction and Fourier transform infrared spectroscopy. SEM confirmed the Walnut morphology of PY and it is maintained in nanocomposites but size of particles has been increased. Consequently, optical band gap (Eg) and thermal stability of samples observed from UV-Visible Spectroscopy and Thermogravimetric analysis get affected. A. C. Conductivity shows the dispersive nature and a significant increase can be seen from PY1 to PY4 i.e. ac conductivity increases with cobalt ferrite composition into the nanocomposites. Dielectric losses were explained using polarization effect and conductivity values of materials. Diamagnetic nature of PY changes into ferromagnetic in the nanocomposites. Electrodes of each sample were prepared using slurry method and their electrochemical analyses were done in 2 M KOH solution. By enhancing thermal stability, electrical conductivity, and capacitance while simultaneously reducing the optical band gap, the integration of Cobalt ferrite into the PY matrix unlocks new avenues for electronic device design. These advancements pave the way for the development of more efficient and sustainable electronic devices.
