Study on the gas sensing property of ZnO and polypyrrole nanocomposite

An effort is made to prepare the ZnO and Polypyrrole composite thin film. ZnO and Polypyrrole sols were prepared using sol-gel technique. Nanocomposite thin film was prepared using spin coating on glass substrates. The gas sensing studies were done for ammonia (NH3) gas by depositing the films on Inter-digital electrodes.
