SnO sub(2)nanoparticles-modified polyaniline films as highly selective, sensitive, reproducible and stable ammonia sensors

Nanocomposites of polyaniline (PANi) and tin oxide (SnO sub(2)) were prepared by adding SnO sub(2) nanoparticles (NPs) in different weight ratios (0%-50%) into the PANi matrix. X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) wer...

Description
Summary:Nanocomposites of polyaniline (PANi) and tin oxide (SnO sub(2)) were prepared by adding SnO sub(2) nanoparticles (NPs) in different weight ratios (0%-50%) into the PANi matrix. X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) were used to form the polyaniline-SnO sub(2) nanocomposites (PANi-SnO sub(2)) - a polymer-composite. PANi films modified with SnO sub(2)NPs were prepared by the spin coating method. The gas sensing properties of PANi, SnO sub(2) and PANi-SnO sub(2) polymercomposite films were observed and it was found that:
