목적: 본 연구는 furfuryl isocyanate를 은 나노 물질(Ag nanoparticler)과 기존의 하이드로젤 곤택트렌즈 재료와 공증합 하였으며, 제조된 콘택트렌즈의 물리적 특성을 비교하고, 내구성이 높은 콘택트렌즈 고분자로서의 활용성을 알아보았다. 방법: 교차결합제인 EGDMA(ethylene glycol dimethacrylate)와 HEMA(2-hydroxyethyl methacry-Late), MMA(methyl methacrylate), MA(merhacrylic acid) 그리고 개시제인 AIBN(azobisisobutyronitrile)과 함께 공증합 하였다. 결과: 생성된 고분자의 물리적 특성을 측정한 결과, 함수율 28.98~34.31%, 굴절률 1.441~1.453,UV-B투고율 33.2~72.0%, 접촉각 57.65~79.00° 그리고 인장강도의 경우 0.340~0.71kgf 범위의 분포를 나타내었다. 또한 은 나노 물질 1%에 furfuryl isocyanate를 첨가할수록 UV-B 투과율 저하와 인장강도가 증가한 결과를 보였다. 결론: 본 실험결과로 볼 때 생성된 공중합체는 내구성이 좋고 자외선 차단 효과가 있는 렌즈 재료로 유용하게 활용될 것으로 기대된다.
Purpose: In this study, we compared the copolymer produced with the furfuryl isocyanate and Ag nanoparticle with previous hydrogel contact lens materials and measured the properties of the produced contact lens in order to experiment whether the material is suitable for contact lens materials with hugh durability. Methods: For copolymerization, furfuryl isocyanate with the cross-linkerEGDMA (ethylene glycol dimethacrylate), HEMA (2-hydroxyethel methacrylate), MMA(methyl methacrylate), MA(methacrylic acid), Ag nanoparticle and the initiator AIBN(azobisisobutyronitrile) were used. Results: Measurement of the physical properties of the copolymerized material showed that the water content, refractive index, UV-B transmittance, contact angle and tensile strength were in the range of 28.98~34.31%, 1.441~1.453, 33.2~72.0%, 57.65~79.00 ° and 0.340~0.713kgf, respectively. Conclusions : Based on the results of this study. The produced copolymer can be estimated to be suitable for usw as hydrogel contact lens material for high durability and uv-blocking.
