Abstract
The control and monitoring of humidity levels and the concentration of hazardous gases in the atmosphere are subjects of significant interest across various fields. Consequently, current research focuses primarily on the advancement of sensitive materials tailored for humidity and toxic gas sensors, aiming to achieve heightened performance and sensitivity while operating efficiently at ambient temperatures. Investigative efforts delve into exploring thin film compositions comprising polyanilines and their derivatives, as well as polymer nanocomposites, with the intention of fabricating chemical sensors. Diverse configurations of chemical sensors, manifesting as thin-film electronic devices such as resistive and transistor structures, are under scrutiny. The surface morphology of these thin films is meticulously examined through scanning electron microscopy. Furthermore, the electrical characteristics, as elucidated by the current-voltage profiles, of resistive and transistor structures utilizing thin films of polyanilines and their derivatives alongside polymer nanocomposites, are analyzed in relation to variations in ambient humidity levels and concentrations of hazardous gases such as ammonia vapors. The outcomes of this investigation underscore the potential utility of organic compound-based thin films in the realm of chemical sensor development.
