Preparation and characterization of PAn-TiO_2 composite film

PAn-TiO2 composite film is electrosynthesized on stainless steel in sulfuric acid media containing aniline and nano-TiO2 particles by cyclic voltammetry.The electrochemical properties and ingredient of composite film were characterized by means of cyclic voltammetry(CV),X-ray diffraction(XRD) and differential scanning caloricity(DSC).The results show that the composite between TiO2 and polyaniline in structure is achieved and the incorporation of TiO2 enhances electric and electrochemical performance of polyaniline film.In article,the method of measuring resistance by layer cell can be used to compare conductivity qualitatively and the further studies on the structure of composite film may be based on the conclusion of the composite between TiO2 and polyaniline in structure.
