| description | The present research article demonstrates the dispersion of manganese dioxide (MnO2) nanoparticles in polythiophene (PTh) to enhance the optical and gas sensing properties of PTh/MnO2 nanocomposites. The structural aspects of the as-synthesized nanocomposites were demonstrated by the techniques such as X-ray diffraction (XRD), Fourier transmission infrared spectroscopy (FTIR), Field emission scanning electron microscopy (FE-SEM). Furthermore, the optical characterization of the resulting composite was investigated using UV–Vis spectroscopy. UV–Vis analyses of obtained nanocomposite revealed a forbidden band of ∼ 3.7 eV. The prepared nanocomposites were exposed to CO2 gas to investigate the composites suitability for gas sensing application, which prove to be promising materials. The prominent exploit of the present work is that 0.8 Wt. % MnO2 loaded PTh composite material exhibits significant sensing response at low operating temperature including good stability and fast response and recovery time. The core objective of this work is the discussion of the enhancement in stability, response and recovery time as a consequence of the interaction between the CO2 gas and the as-synthesized nanocomposites. |
