Abstract	최근 금(Au)과 은(Ag) 나노입자는 항균성의 특징으로 다양한 분야에서 응용되고 있다. 본 연구는 HEMA (2-hydroxyethylmethacrylate), NVP (N-vinyl pyrrolidone) MMA (methylmethacrylate)에 금과 은 나노입자를 첨가하였으며, 70 ^oC에서 약 40분, 80 ^oC에서 약 40분 마지막으로 100 ^oC에서 약 40분 동안의 열처리 공정을 거쳐 공중합 하였다. 중합 과정을 거쳐 중합된 고분자를 통해 물리적 특성을 측정한 결과, 함수율 28.43% ~ 35.27%, 굴절률 1.429 ~ 1.440를 나타내었으며, 가시 광선 투과율 79.2% ~ 86.5% 그리고 인장강도 값은 0.125 kgf ~ 0.201 kgf을 나타내었다. 본 실험 결과로 볼 때 항균성을 가 지면서 기존의 콘택트렌즈의 물리적 특성에도 부합되는 공중합체가 생성된 것으로 판단된다. Recently, nanoparticles of gold and silver has been applied to various fields due to antimicrobial property. This study added Ag and Au nanoparticles in HEMA (2-hydroxyethylmethacrylate), NVP (N-vinyl pyrrolidone) and MMA (methylmethacrylate) and copolymerized the solution by heating at 70 ^oC for 40 minutes, 80 ^oC for 40 minutes, and finally, 100 ^oC for 40 minutes. Using the polymer produced through the copolymerization process, and measured the physical characteristics which showed water content of 28.43% ~ 35.27%, refractive index of 1.429 ~ 1.440, visible transmittance of 79.2% ~ 86.5% and tensile strength of 0.125 kgf ~ 0.201 kgf. We judged that we made the copolymer with antimicrobial and physical properties which is suitable for conventional contact lens.
