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.
