Abstract

In this study, rapid cooling method was proposed to improve the anti-scratch performance of anti-reflection film fabricated by nanoimprint lithography. Effects of cooling time on the mechanical properties and optical properties were evaluated. Pencil hardness measurements showed that anti-scratch performance enhanced as the cooling time increased while characterization on the optical property showed that reflectance on scratch increased as the cooling time increased. Therefore, it was concluded that the anti-scratch performance and optical properties are highly influenced by the cooling time. The observed results explained in terms of residual stress and free volume in polymeric materials.

본고에서는 임프린트로 제작된 저반사 필름의 내스크래치 특성 향상을 위해 급속 냉각 방법을 제안하였다. 냉각시간을 변수로 하여 기계적인 특성과 광학적 특성에 대한 영향을 평가하였다. 냉각 시간에 따른 기계적 특성 평가 결과 냉각 시간이 증가할수록 내스크래치 특성이 향상되는 거동을 보였지만, 광학적 특성 평가 결과 냉각 시간이 증가할수록 스크래치 발생 부분의 반사율이 매우 증가하는 경향을 보였다. 이를 통하여 냉각 시간에 따라 잔류 응력 변화가 발생하고 나노 구조 표면 형상에 영향을 주어 내스크래치 특성 및 광학적 특성에 영향을 줄 수 있음을 확인하였다.
