| Popis: |
Synthesis conditions of doped polyaniline films and testing procedure affect markedly the sensor behavior and stability of them. The sensor based on such film consists of a dielectric substrate with system of metallic interdigitated electrodes on its surface. The films were deposited on system of metallic interdigitated electrodes by electrochemical synthesis from solutions of aniline with different polyoxometalates and acids. Activating additives into films were tungsten containing polyoxometalates of the eighteen series. Polyoxometalates as multielectron oxidants can alter noticeably the sensor properties of polyaniline if introduced into a conductive polymer film. Morphology of the layers surface and the infrared spectra were explored. Investigations of the behavior of polyoxometalate-polyaniline films at different temperatures, air humidity and testing procedures in clean air and in air containing ammonia were fulfilled. |
