Abstract: In this paper, Polyepichlorohyron(PECH)/multi-wall carbon nanotubes(MWCNTs) composite films and PECH/multi-wall carbon nanotubes twolayer film were deposited on interdigitated electrodes by airbrush technology to detect ethanol vapor of various concentrations at room temperature. Thickness and structure of the film were taken into account, so films of different thicknesses and with different structures were prepared respectively. The responses of the sensors to ethanol showed that composite film had a higher response thantwolayer film, and the thick composite film performed better than its counterpart when they were exposed to ethanol vapor.

The nanocomposite of polyaniline (PAni)-coated Carbon nanotubes (CNT) for NH3gas sensing application are presented in this paper. The nanorods of PAni/CNT nanocomposite was synthesized by chemical oxidative polymerization of aniline using ammonium persulfate in acidic medium. The aniline was adsorbed in CNT by vacuum absorption method. The morphologies and properties of the nanocomposite have been characterized by SEM, XRD and FTIR respectively. Thin sensor of PAni/CNT nanorods was prepared by spin coating method. Finally, the response of these composite films for NH3gas was evaluated by monitoring the change in electrical resistance at room temperature. With compared to the pure PAni and CNT, tSubscript texthe nanorods of PAni/CNT composite films show a higher sensitivity.
