A facile solid-state approach was used to prepare polypyrrole-tin oxide (PPy–SnO2) (0–50 wt%) hybrid nanocomposites (NCs). The structure and morphology of the hybrid NCs were characterized using X-ray photoelectron spectroscopy, X-ray diffraction (XRD), Fourier transform infrared (FTIR), ultraviolet–visible (UV–Vis), field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and atomic force microscopy (AFM) measurement techniques. Two point-probe method was used to study electrical transport properties of PPy–SnO2 hybrid NCs. The structures of SnO2 as well as PPy–SnO2 hybrid NCs (0–50%) were confirmed from the XRD patterns. The FESEM surface images of the hybrid NCs reveal uniform distribution of the SnO2 nanoparticles (NPs) in the PPy matrix. The characteristic FTIR peaks of PPy and UV–Vis absorption wavelength shift to a higher wavenumber and wavelength sides in PPy–SnO2 hybrid NCs, which are attributed to interaction of SnO2 NPs with PPy molecular chains. The negatively charged O2− surface of SnO2-NPs transfers electrons to polypyrrole which is in its highly reduced form. A strong localization of charge carriers in the reduced polypyrrole makes PPy–SnO2 hybrid NCs highly resistive.
