초록

광학렌즈용 정전기 방지 코팅은 대전방지 기능 외에도 적합한 광학적, 기계적 물성을 보유하고 있어야 한다. 본 연구에서는, 이미다졸계 코팅액을 제조하고, 이를 투명 기판 표면에 중합하여 정전기 방지 코팅을 제조하고자 하였다. 제조된 코팅은 우수한 부착력과 가시광선 투과율을 보였으며, 유기용매 및 온수, 비눗물에 안정성을 보였다. 이미다졸 농도가 증가함에 따라 대전되는 정전기의 양이 감소하였으며, 2% 이상의 구간에서는 30-50% 습도환경에서 우수한 대전방지능을 보였다. 또한 적은 양의 이미다졸을 첨가하는 것만으로도 일반적인 습도환경에서 대전된 정전기가 약 2초의 반감기를 보이면서 빠르게 감쇠하였다. 이러한 대전 방지 기능은 이미다졸이 4% 이상이었을 때, 8주 이상 유지되는 것으로 확인되었다. 이미다졸을 포함하는 아크릴레이트 코팅은 뛰어난 내구성의 대전 방지기능을 나타냈으며 광학적 특성도 우수하여 여러 광학용 재질에 응용될 수 있을 것으로 보인다.

Several aspects in optical quality and mechanical resistance have been considered in development of optical coating. In this study, imidazole-based anti-static solution was copolymerized on surfaces of optical lenses. The coated lenses showed high quality of optical properties and resistance to organic solvents, surfactants, and warm water. Electrostatic potentials on the coating membrane decreased with increasing composition of imidazole, while more than 2% imidazole coats showed considerable anti-static capability in 30-50% humidity conditions. Furthermore, short half-life of electrostatic potentials, approximately 2 sec, was observed in the groups of 1% imidazole coat in the ambient humidity condition. This anti-static function had been retained for more than 8 weeks, when 4% of imidazole was composed in coating solutions. The present imidazole-based acrylate polymer coating exhibited durability, comparable anti-statics capability, and optical property. Thus, it is expected to facilitate the functionalization of various optical materials.
