Synthesis, Characterization and Study of H2S Gas Sensing Properties of CdO Doped in Nanocrystalline Pollyaniline

M. S. Phalak, R. B. Waghulade

Polyaniline PANI and CdO/ PANI nano composites were synthesized by in situ polymerization technique and characterized by Fourier transform infrared spectra (FTIR), X-Ray diffractometer (XRD), Field Emission Gun Scanning Electron Microscopy (FEG SEM), which confirms the presence of CdO in PANI matrix. The synthesized materials were further used for sensing various gases like LPG, NH3, CO2 and H2S gas. The change in resistant of the material with time was recorded after the response of H2S gas. The increase in electrical resistance is due to transfer of charge from sensing material to analyse gas and absorption of gas into the polymer matrix. The sensitivity was found maximum for H2S. The 50 wt % CdO/PANI nano composite showed maximum sensitivity (300 %) for 400ppm of H2S gas
