In this paper, GO was obtained by using chemical oxidation method at room temperature, and nano/micro-structured GO/PANi composite was prepared with in-situ polymerization of aniline in the presence of GO suspension. A series of characterizations were examined by TEM (transmission electron microscopy), AFM (Atomic Force Microscope), XRD (X-ray diffraction), the Fourier-Transform Infrared (FTIR) spectra, UV-Vis, et al. To examine the surface and interface properties of GO, GO/PANi nanocomposite, chemical prototype sensors were constructed based on GO, GO/PANi nanocomposite and QCM device. The comparative response behaviors of the sensor to some typical volatile compounds operating at room temperature were investigated. The adsorption features to some typical volatile compounds were discussed. Some key issues and modification ideas were suggested for further investigation.-
