Title: Development of Fe 2 O 3 –PANI nanocomposite thin film based sensor for NO 2 detection
Abstract: The iron oxide-polyaniline (α-Fe2O3–PANI) films were prepared by spin coating method on various corning glass substrates over Pt inter-digital electrodes (IDEs). The prepared film was characterised using XRD, SEM, AFM, UV-vis and FTIR. Also, it was employed for NO2 sensing. The nanostructured α-Fe2O3–PANI film showed a high sensing response ∼2.29 × 102 towards 20 ppm of NO2 gas. Besides giving the higher sensing response towards NO2 gas, α-Fe2O3–PANI sensor structure was found to be highly selective and exhibited the poor gas sensing response towards other interfering gases including e.g. Acetone, IPA, NH3, LPG and CO2. The investigated sensor can be used for the detection of NO2 at the industrial level.
