Abstract

코팅은 플라스틱의 표면의 물성과 렌즈의 광학적 성능을 높이기 위해 필요하다. Allyl diglycol carbonate계열 렌즈의 표면의 물성과 광학적 성능을 개선하기 위하여 3-glycidoxypropyltrimethoxysilane(GPTS), methyltrimethoxysilane(MTMS) 및 tetraethyl orthosilicate(TEOS)의 몰 비를 변화시켜 유-무기 하이브리드 재료로 사용하였다. Sol-gel 공정에 의한 flow코팅하여, $140^{\circ}C$ 에서 4시간 경화하였다. 코팅 렌즈는 투과율, 부착력, 연필경도, 내마모성, 내온수성 및 내약품성을 평가하였고 GPTS, MTMS 및 TEOS의 몰 비가 각각 1:1:2일 때 가장 우수한 것으로 나타났다. 【Coating are needed on ophthalmic lenses to enhance both the mechanical durability of the relatively soft plastic surface and the optical performance of lenses. Organic-inorganic hybrid materials as molar ratio of 3-glycidoxypropyltrimethoxysilane(GPTS), methyltrimethoxysilane(MTMS) and tetraethyl orthosilicate(TEOS) were used to improve the surface characteristics and the optical properties on allyl diglycol carbonate lenses. Coating for these plastics were at $140^{\circ}C$ for 4hrs, applied using the sol-grl process flow-coating technique. The coated lens properties of transmittance, adhesion, pencil hardness, abrasion resistance, hot water resistance and chemical resistance were investigated. The optimum properties was obtained when the ratio of GPTS : MTMS : TEOS was 1:1:2, respectively.】
