Nanocomposites of polyaniline (PANi) and tin oxide (SnO2) were prepared by adding SnO2 nanoparticles in different weight ratios (10-50%) into the PANi matrix. The nanocomposites thin films were characterized for their structural and chemical properties using XRD, FESEM and TEM, which confirms the formation of polyaniline-SnO2 nanocomposites. The room temperature gas sensing properties of nanocomposite films were studied for various reducing and oxidizing gases. We demonstrate that PANi-SnO2(50%) nanocomposite films are highly selective to NH3 along with maximum response and better stability at room temperature.
