| Popis: | Polyaniline thin films doped with an inorganic acid were deposited on glass substrate using simple and cost effective oxidative polymerization technique. As- synthesized thin film of polyaniline was studied with dif- ferent characterization techniques. The formation of polyaniline on glass substrate was confirmed by X-ray diffraction and UV spectroscopy. Surface morphological investigation was performed using scanning electron mi- croscopy. Gas sensing behavior of polyaniline thin film was studied by I-V measurements before and after lique- fied petroleum gas (LPG) exposure at room temperature, based on change in electrical resistance. The observed re- sult shows polyaniline thin film sensor is efficient for LPG detection at room temperature. |
