This study systematically analyzed the effects of surfactant type and amount of water on the key properties of contact lenses under room-temperature polymerization conditions. This study aims to establish a design foundation for contact lens materials and suggest the possibility of room-temperature polymerization-based process optimization. Contact lenses were fabricated using hydrophilic monomers, initiators, initiation catalysts, and cross-linkers. Twenty-one contact lenses were fabricated using four nonionic surfactants and varying water content. Compared to thermally polymerized contact lenses, room-temperature polymerized contact lenses containing surfactants and water exhibited superior moisture content, oxygen transmissibility, and wettability. Even when the same surfactant was used, the properties varied significantly depending on the water content, and lenses prepared with Tween-based polymers exhibited lower light transmittance, limiting their practical usability. Protein adsorption was lowest when 30% water and P188 were used. This study confirmed that surfactant and water content significantly influence the properties of room-temperature polymerized contact lenses.
상온중합 조건에서 계면활성제 종류와 물 함량 변화가 콘택트렌즈의 주요 특성에 미치는 영향을 체계적으로 분석하여, 콘택트렌즈 소재의 설계 기반을 마련하고, 상온중합 기반의 공정 최적화 가능성을 제시하고자 한다. 콘택트렌즈 제작은 친수성 단량체, 개시제, 개시반응 촉진제, 교차결합제를 포함하였으며, 비이온성 계면활성제 4종과 물 함량 변화에 따라 21종을 제작하였다. 열중합 콘택트렌즈에 비해 계면활성제와 물이 포함된 상온중합 콘택트렌즈는 함수율, 산소전달성, 그리고 습윤성이 우수하였다. 동일 계면활성제 사용 시에도 물 함량에 따라 특성이 많이 변하였으며, tween 계열을 사용한 렌즈는 빛 투과도가 낮아서 활용성이 저하되었다. 단백질흡착은 물 30%, P188을 사용하였을 때 가장 낮았다. 이로써 계면활성제와 물 함량이 상온중합 콘택트렌즈의 특성 변화에 많은 영향을 미친다는 것을 확인하였다.
Keywords: contact lens, room temperature polymerization, surfactant, wettability, oxygen transmissibility.
