ABSTRACT

In this study, the development of transparent UV blocking material using TiO2−x oxide thin film process wasdeveloped. A process technology is related to a process technology for making a sample with ultraviolet-shielding propertyof visible light transmittance of 78 % or more (total light transmittance at 550 nm) and of a UV cut-off characteristic ofmore than 95 % at 315 nm in ultraviolet wavelength band. In this study, it is possible to establish a flexible device processcondition of high performance ultraviolet (UV) shielding thin film, to design mixed type of transparent flexible device withheterogeneous characteristics and to formulate composite deposition technology, according to various market demands. Establishment of actual roll-to-roll continuous process and equipment and process technology will affect related industriesgreatly.
