Films of salt and base were characterized by optical absorbance spectroscopy which reveals the formation of polyaniline. The resistivity of both samples was investigated by I-V source meter which shows ohmic nature. Surface morphology of both samples was investigated by Field Emission Scanning Electron Microscopy, which represents the nanostructured and granular morphology. Ammonia sensing properties of both samples were by I-V source meter in presence of 25 ppm of ammonia. Observed values of sensitivity (S) is 82% and 56% for polyaniline salt and polyaniline base.Read More
