Abstract

We investigated the change in the characteristics of contact lenses according to the interpenetrating polymer network (IPN) time and method when a contact lens was dual-networked with alginate and carrageenan. The IPN was formed for four weeks using semi-IPN and full-IPN. The functions of contact lenses were assessed based on the measurement of water content, oxygen permeability, contact angle, protein adsorption, and antimicrobial. With the increase in IPN time, all physical and chemical properties of contact lenses were improved. The oxygen permeability and wettability were better when using alginate than using carrageenan. The water content and oxygen permeability were better when using the semi-IPN method than using the full-IPN method, whereas wettability was further improved when using the full-IPN method. The result of this study verified that seaweed polysaccharides were helpful in the functional improvement of hydrogel contact lenses, and performance was better in a longer IPN time.


본 연구는 하이드로겔 콘택트렌즈에 알지네이트와 카라기난과 같은 해조다당류를 상호침투 고분자 네트워크를 진행하여 interpenetrating polymer network(IPN) 시간에 따른 콘택트렌즈의 특성 변화를 살펴보았다. IPN은 알지네이트와 카라기난을 이용하여 semi-IPN과 full-IPN으로 4주 동안 진행하였다. 콘택트렌즈의 기능은 함수율, 산소투과율, 접촉각, 단백질 흡착, 그리고 항균성 등을 측정하여 평가하였다. IPN 시간이 증가함에 따라 콘택트렌즈의 모든 물리·화학적 성질이 향상되었다. 산소과율과 습윤성은 카라기난보다 알지네이트를 사용했을 때가 더 높았다. 함수율과 산소투과율은 semi-IPN 방법이 full-IPN 방법보다 좋았으며 습윤성은 full-IPN 방법이 더 많이 향상되었다. 해조다당류는 하이드로겔 콘택트렌즈의 기능 향상에 도움이 되며 IPN 시간이 길수록 성능이 더욱 증가함을 확인하였다.
