알루미나 졸과 아크릴레이트 단량체를 이용한 UV경화형 유-무기 하이브리드 하드코팅 막 제조
Preparation of UV-Curable Organic-Inorganic Hybrid Hard Coating Films Using Alumina Sols and Acrylate Monomers
황지현, 송기창
본 연구에서는 알루미나 졸과 아크릴레이트 단량체를 이용하여 UV 경화형 유-무기 하이브리드 하드코팅 용액을 제조하였다. Aluminum isopropoxide로부터 얻어진 알루미나 졸에 실란커플링제인 methacryloxypropyl trimethoxysilane(MPTMS)을 첨가하여 제조된 졸을 무기물 성분으로 사용하였다. 유기물 성분으로는 다양한 아크릴레이트 단량체인 pentaerythritol triacrylate(PETA), 1,6-hexanediol diacrylate(HDDA), dipentaerythritol hexaacrylate (DPEHA)를 혼합하여 사용하였다. 이후 무기물 성분과 유기물 성분을 혼합하여 유-무기 하이브리드 코팅 용액을 제조한 후, 이를 polycarbonate 기판 위에 스핀 코팅 후 UV 경화를 실시하여 도막을 형성하였다. 이때 무기물 성분 중의 MPTMS의 첨가량과 UV 경화 시간 변화가 코팅 막의 물성에 미치는 영향을 연구하였다. 그 결과 MPTMS가 0.20 mole 첨가 될 경우 코팅 막은 3H의 우수한 연필경도를 나타내었으며 haze값이 2%로 내마모성도 우수하였다.
In this study, UV-curing type organic - inorganic hybrid hard coating solutions were prepared from alumina sols and acrylate monomers. The mixture of alumina sols, prepared from aluminum isopropoxide, and a silane coupling agent, methacryloxypropyl trimethoxysilane(MPTMS), was used as an inorganic component. Also, the mixture of acrylate monomers, pentaerythritol triacrylate(PETA), 1,6-hexanediol diacrylate(HDDA) and dipentaerythritol hexaacrylate (DPEHA), was used as an organic component. The organic-inorganic hybrid coating solutions were obtained by mixing the inorganic component and organic component, deposited on polycarbonate substrates by spin coating and densified by UV-curing. The effect of the amount of MPTMS in the inorganic component and the irradiation time during UV-curing was studied on the properties of coating films. As a result, when 0.20 mole of MPTMS was used, the pencil hardness of coated films showed an excellent pencil hardness of 3H and also exhibited a good abrasion resistance of 2% in haze.
