초록

가시광촉매의 특성 및 가시광촉매가 코팅처리된 자동차내장재 nylon/polyester 복합섬유에 대한 VOCs의 저감에 대해 알아보았다. 가시광촉매 Weltouch의 결정구조는 아나타제상과 루타일상이 복합된 것으로 약 420nm이상의 파장을 갖는 빛에너지에서도 활성을 나타냈다. 또한 가시광촉매가 처리된 자동차내장재 nylon/polyester 복합 섬유에서 발생하는 VOCs 및 포름알데히드는 현저한 저감효과를 나타냈으며, 섬유를 25회 세탁을 행하여도 가시광촉매의 탈락없이 표면에 견고하게 부착되어 가스분해성능을 유지하는 것으로 나타나서 세탁내구성이 우수한 것을 확인하였다.

In this study, characteristics of visible-light responsive photocatalyst Weltouch, especially VOCs reduction of visible-light responsive photocatalyst coated nylon/polyester composite fiber for vehicle interior parts and materials were evaluated. Visible-light responsive photocatalyst Weltouch was observed for both anatase phase and rutile phase. It is activated by light longer than 420nm. VOCs and formaldehyde generated from visible-light responsive photocatalyst treated nylon/polyester composite fiber were reduced confirmly. Visible-light responsive photocatalyst was firmly attached to the surface of nylon/polyester composite fiber without elimination even after 25 times repeated washing. And washing durability of nylon/polyester composite fiber confirmed the excellence that reduction effects of VOCs after repeated washing has appeared as much as before washing.
