온도감응성 하이드로젤과 은 나노패턴 기판으로 구성된 유연한 태양광 차단용 스마트 필름의 투광도 특성 연구

다국어 초록 (Multilingual Abstract)

Smart windows adaptively screen the sunlight that enters into the room, thereby reducing the cooling cost by restraining the increase of room temperature. Traditional glass-based smart windows have been extensively studied, but it is difficult to manufacture the curved or flexible glazings. In this study, we developed a film-type hybrid smart windows that can show the tansmittance change in response to both external temperature and electric energy, which is achieved by using the thermosensitive hydrogel and transparent silver nanopatterned film. The thermosensitive hydrogel was injected in the space between the films, and the optical transition from transparent to opaque state can be induced by the phase transition of the thermosensitive hydrogel. We found that the silver nanopatterned films effectively generated the heat by the Joule-heating mechasim, leading the phase transition of the hydrogels. Consequently, the aggregated hydrogel chain scattered the light passing through the film, reducing the optical transmittance.
