In this work RGO-SnO2 (RGS) nanocomposites were synthesized by ex-situ polymerization method by varying the concentrations of RGO nanoparticles in SnO2 matrix (0, 5, 10, 15, 20 wt%). The synthesized nanocomposites were subjected to structural characterizations viz, X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FESEM) techniques. XRD and FTIR spectroscopic studies reveals the presence of characteristic bands of both RGO, SnO2 nanoparticles and formation of their composites confirmed with the interfacial interaction of RGO nanoparticles in the SnO2 systems. FESEM images of RGS nanocomposites depicts the spherical morphology. Electrical properties of the synthesized samples were studied with respect to the frequency range 100 Hz to 5 MHz at room temperature. The gas sensing performance of the RGS nanocomposites were studied at 3 different temperatures (200, 250, 300 0C) for 4500 PPM of ethanol vapors and at 3000C the sample 90SnO2:10RGO shows ~145% of sensitivity with the good response of 18 s and recovery time of 194 s.
