Zusammenfassung:Nanoparticle with antimicrobial property has been applied to various fields. This study added silver/platinum nanoparticles to HEMA (2-hydroxyethylmethacrylate), NVP (N-vinyl pyrrolidone) and MMA (methylmethacrylate) in various concentrations and copolymerized by heating at $70^{\circ}C$ for 40 minutes, $80^{\circ}C$ for 40 minutes, and finally, $100^{\circ}C$ for 40 minutes. The particle size of used nano silver and platinum was 10 ~ 20 nm respectively. Using the polymer produced through the copolymerization process, the authors have produced a contact lens and measured the physical characteristics which showed water content of 34.29 ~ 39.00%, refractive index of 1.422 ~ 1.430, visible transmittance of 78.8 ~ 92.5% and tensile strength of 0.149 ~ 0.179 kgf. The ophthalmic lens material produced using silver/platinum nanoparticles satisfied the basic physical properties required for contact lens application. 항균성을 포함한 나노 입자는 높은 활용성으로 인해 다양한 분야에 적용되고 있다. 본 연구는 HEMA (2-hydroxyethylmethacrylate), NVP (N-vinyl pyrrolidone), MMA (methylmethacrylate)에 나노 은 및 백금을 첨가한 후 농도조건을 다양화 하여 $70^{\circ}C$에서 약 40분, $80^{\circ}C$에서 약 40분 마지막으로 $100^{\circ}C$에서 약 40분 동안의 열처리 공정을 거쳐 공중합 하였다. 사용된 나노 은과 백금 입자의 크기는 각각 10 ~ 20 nm를 나타내었다. 중합 후 생성된 고분자를 사용하여 물리적 특성을 측정한 결과, 함수율 34.29 ~ 39.00%, 굴절률 1.422 ~ 1.430을 나타내었으며, 가시광선 투과율 78.8 ~ 92.5% 그리고 인장강도 값은 0.149 ~ 0.179 Kgf을 나타내었다. 나노 은과 백금 입자를 사용한 안 의료용 렌즈 재료는 콘택트렌즈 적용에 요구되는 기본적인 물성을 만족하였다.
