AP0988 Preparation and Characterization of PANI/GO/WO3 Nanocomposites: Structural Properties and Their Applications in Gas Sensing

Abstract

This work aims to examine the synthesis, optical properties, and gas-sensing abilities of PANI/GO/WO₃ nanocomposites. An FTIR study was conducted to examine the chemical contents of nanocomposites. The synthesis effort commenced with the application of chemical oxidative polymerization of polyaniline (PANI). The detection of H₂S gas was assessed across an extensive temperature range. The integration of metal oxide (WO₃) and graphene oxide (GO) into the PANI matrix led to a reduction in structural stability. The findings indicated that the integration of these two materials enhanced gas detection. The nanocomposites exhibited exceptional performance due to their enhanced sensitivity, rapid response time, and selectivity for H₂S, even under elevated temperatures. Research has shown that nanocomposites composed of PANI, GO, and WO₃ has the capability for gas sensing applications in agricultural and industrial monitoring. Future experiments should concentrate on refining the material composition and processing parameters to improve the system's sensitivity, selectivity, and long-term operational stability.
