This study uses the atmospheric pressure plasma polymerization method to utilize monomer W(CO)6 and Ta(OCH2)6 preparation of flexible electrochromic film for tungsten-Tantaium oxide deposited on PET/ITO (Polyethyleneterephthate/Indium Tin Oxide) plastic substrate. Because the advantages of this process are fast and low cost, vacuum equipment and vacuum chambers are not required. Therefore without the need of vacuum chambers, there are no limitations to the size of the substrate dictated by vacuum chambers. This increases the fast thin film coating speed. So this conforms to the industrial requirements to be able to meet mass production condition. Tantalum oxide film has many advantages such as high ionic conductivity and low packing density, high penetration, high dielectric constant, good chemical and thermal stability of the adverse. Tantalum oxide mixed into the tungsten oxide film in order to enhance their optical, electrochemical, electrochromic properties.
Study the effects of different operating parameters such as changes in Oxygen flow rate or Ta percent. PET/ITO/WxTa1-xO3, produced by the atmospheric pressure plasma, and probes into the electrochemical properties, optical properties and electrochromic properties by utilizing three methods: the cyclic-voltamogram method, the step method and the UV-VIS spectroscopy method. A Field Emission Scanning Electron Microscope was used to analyze the film thickness and its surface morphology.
