摘要：
In the present work we have synthesized PANI by in-situ chemical oxidative polymerization method. The chemiresistor type gas sensors have been fabricated by deposited tantalum and polyaniline composite thin film on to interdigited electrodes (IDE) configuration using sputtering ad spin coating techniques respectively. The composite thin film was irradiated using 150 MeV Au+7 at the fluence of 1x 10(11) ions/cm(2). The pristine Ta/PANI composite sensor showed negligible sensing response which was further improved up to 1.42 ((i.e. %Sensitivity approximate to 30%) after SHI irradiation. The structural and morphological properties of composite sensing thin films have also been characterized by XRD and AFM measurement before and after SHI irradiation.
