Preparation and Characterization of Polyaniline/ZnO Composite Sensor
ثبت نشده
چکیده
Polyaniline/ZnO nanocomposite thin films were prepared via an electrochemical synthesis route on ITO coated glass substrates. ZnO nanoparticles were uniformly dispersed in to the polyaniline matrix. Interaction between ZnO nanoparticle and polyaniline has been studied using X-ray diffraction (XRD), UV-Vis absorption spectroscopy, PL spectroscopy, AFM and I-V characteristics. The ammonia gas sensing behaviors of the polyaniline/ZnO composites were examined at room temperature. It was observed that the composite films showed good sensitivity, improved doping state and enhanced photoluminescence behaviour.

A polyaniline/In2O3 nanofiber composite based layered surface acoustic wave (SAW) sensor has been developed and investigated towards different gases. Chemical oxidative polymerization of aniline in the presence of finely divided In2O3 was employed to synthesize a polyaniline nanofiber/In2O3 nanoparticle composite. The nanocomposite was deposited onto a layered ZnO/64° YX LiNbO3 SAW transducer. ...
