Abstract

In this study, the development of transparent UV blocking material using $TiO_{2-x}$ oxide thin film process was developed. A process technology is related to a process technology for making a sample with ultraviolet-shielding property of visible light transmittance of 78 % or more (total light transmittance at 550 nm) and of a UV cut-off characteristic of more than 95 % at 315 nm in ultraviolet wavelength band. In this study, it is possible to establish a flexible device process condition of high performance ultraviolet (UV) shielding thin film, to design mixed type of transparent flexible device with heterogeneous 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 industries greatly.

본 연구에서는 $TiO_{2-x}$ 산화물 박막공정을 이용한 유해 자외선차단 투명 유연 소재를 개발하고자한다. 자외선 차단 특성: 자외선 파장대의 315 nm 차단율이 95 % 이상이면서, 자외선차단특성을 갖으면서 투명성을 높인 가시광선 투과율 78 % 이상(550 nm에서 전광투과율)의 시료를 만드는 공정기술을 개발하고자 하였다. 본 연구 결과로 고성능 자외선차단 박막의 유연 소자 공정조건을 확립하고, 이질성 특성의 투명 유연 소자의 혼합형 설계와 시장 요구에 다양하게 대응이 가능한 복합 증착 기술 정립, 롤투롤(roll-to-roll) 연속 공정의 실현 및 장비, 공정 국산화 기술 확립으로써 관련 산업으로의 기술 파급 효과가 클 것으로 사료된다.
