초록

본 연구에서는 자외선 흡수 물질로 잘 알려진 zinc oxide (ZnO) 나노분말을 세 가지 합성조건에서 수열합성법으로 합성하였다. 또한, 분산성을 향상시키기 위하여 합성된 ZnO 나노분말의 표면을 다양한 실란계 계면활성제를 사용하여 표면개질하였고, 표면개질된 ZnO 나노분말을 분산제로 72 h 동안 볼밀링하여 분산 졸 시료를 제조하였다. 30 nm 크기로 합성된 ZnO 나노분말을 3-chloropropyl trimethoxy silane로 표면개질하여 폴리우레탄계 분산제로 제조한 분산 졸 시료가 가장 높은 자외선 차단 특성 및 가시광 투과율을 가지면서 분산 안정성이 가장 우수하였다.

In this study, zinc oxide (ZnO) nano powder, well known as an UV absorbing material, was synthesized with three synthetic conditions by the hydrothermal method. After ZnO nano powder was surface-modified with various silane coupling agents to improve dispersion property, a dispersion sol was prepared with dispersant for 72 h by the ball-milling of surface-modified ZnO nano powder. The dispersion sol, prepared by modifying the surface of the ZnO nano powder with an average size of about 30 nm using 3-chloropropyl trimethoxy silane, showed an excellent dispersion stability with a high UV-shielding and visible trnasparency.
