Abstract

Herein present study, organic-inorganic hybrids based on WO₃/PANI nanocomposites have been synthesized at room temperature, by using oxidative polymerization. The as-synthesized products have been studied by using X-ray diffraction analysis, FE-SEM and optical characterization. The XRD analysis depicts peak broadening and the shift in peak position from standard values, which can be attributed to the formation of WO₃ in the polyaniline matrix. Study of FE-SEM micrograph revealed that the cube-like WO₃ particles get well dispersed in PANI matrix. WO₃/PANI composite shows enhanced response and recovery time towards ammonia gas at room temperature.
