Synthesized Polyaniline -Polyvinyl alcohol Composites thin films modified by dopant like Iron chloride in situ chemical oxidative polymerization, for ammine hazardous chemical gas sensor. These polymer materials were characterized by Chemical analyses, spectral studies UV-visible and FTIR and conductivity measurement. The surface morphology as seen in the SEM image was observed to be granular, uniformly covering the entire substrate surface. The I–V characterizations show that these thin films have ohmic behaviors. The Polyaniline -Polyvinyl alcohol Composites thin films were used for different concentration (ppm) of ammine hazardous chemical gas investigation at room temperature (304k) for lower ppm concentration.
