Abstract

Catechol 단량체를 dopamine과 methacrylic anhydride와의 반응을 통해 합성하였다. 이후, 2-hydroxy ethylmethacrylate(HEMA), ethylene glycol dimethacrylate(EGDMA), 2-methacryloyloxyethyl phosphorylcholine (MPC)과 공중합한 후, 염기 조건에서 산화반응을 수행하여 ortho-benzoquinone을 기반으로 하는 갈색 투명한 청색광 차단 수화젤 렌즈를 제조하였다. 제조 시, catechol 단량체의 첨가량에 따라, 청색광 차단 정도를 조절할 수 있었으며, 최대 38%까지 청색광을 차단하였다. 또한 UV-A 및 UV-B 영역도 차단하는 효과를 보였다. 제조된 렌즈들은 87% 이상의 평균 가시광선 투과율을 보였다. 함수율과 접촉각은 각각 60% 이상, 60° 미만의 수치를 나타내어, 렌즈 내부 및 표면에서의 친수성이 우수하다는 것을 알 수 있었다.
