Thin Films of Polyaniline-Based Nanocomposites with CeO₂ and WO₃ Metal Oxides Applied to the Impedimetric and Capacitive Transducer Stages in Chemical Sensors.

ABSTRACT: There is a recognized need for the development of cost-effective, stable, fast, and optimized novel materials for technological applications. Substantial research has been undertaken on the role of polymeric nanocomposites in sensing applications. However, the use of PANI-based nanocomposites in impedimetric and capacitive electrochemical sensors has yet to be understood. The present study aimed to explore the relationship between the sensitivity and linearity of electrochemical pH sensors and the composition of nanocomposites. Thin films of PANI/CeO₂ and PANI/WO₃ were deposited via spin coating for characterization and application during the electrochemical impedance and capacitance spectroscopy (EIS and ECS) transduction stages. The findings showed that the optimize
