Abstract

Catechol monomer was synthesized by the reaction of dopamine and methacrylic anhydride. Then, it was copolymerized with 2-hydroxy ethylmethacrylate (HEMA), ethylene glycol dimethacrylate (EGDMA), 2-methacryloyloxyethyl phosphorylcholine (MPC). Subsequent oxidation reaction under a basic condition produced transparent and brownish blue-light blocking hydrogel contact lenses (BB Lenses) based on ortho-benzoquinone. Degree of the blue-light blocking could be controlled depending on the amount of catechol monomer at the initial mixing step of monomers. The maximum blue light blocking ratio was determined to be 38%, and the BB lenses also blocked UV-A and UV-B. The BB lenses exhibited high luminous transmittances more than 87%. The water content and contact angle values were more than 60% and less than 60o, respectively, indicating excellent hydrophilicity both interior and surface of lenses


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, 60o 미만의 수치를 나타내어, 렌즈 내부 및 표면에서의 친수성이 우수하다는 것을 알 수 있었다.
