Abstract

UV-curable hydrophilic coating solutions were prepared by mixing colloidal silica dispersed in alcohol with an acrylic monomer, pentaerythritol triacrylate (PETA). Hydrophilic coating films were also prepared by spin coating the hydrophilic coating solutions on PC substrates and UV curing for 10 minutes subsequently. The effect of the amount of colloidal silica in the coating solutions, which was varied from 10 g to 50 g, was investigated on the hydrophilic properties of UV-cured coating films. The results showed that the amount of colloidal silica had a great influence on the hydrophilic properties of UV-cured coating films and the coating film prepared with 30 g of colloidal silica showed a lowest contact angle of $37^{\circ}$ and an excellent pencil hardness of H.

알코올에 분산된 콜로이드 실리카를 아크릴 단량체인 pentaerythritol triacrylate (PETA)와 혼합시킴에 의해 UV 경화형 친수성 코팅 용액을 제조하였다. 또한 이 친수성 코팅 용액을 PC 기재 위에 스핀코팅 시킨 후 10 min 동안 UV 경화시킴에 의해 친수성 코팅 도막이 제조되었다. 이 과정 중 코팅 용액 중의 콜로이드 실리카 양을 10~50 g으로 변화시켜 코팅 도막의 친수성에 미치는 영향을 살펴보았다. 그 결과 코팅 용액 중의 콜로이드 실리카 양은 코팅 도막의 친수성에 큰 영향을 미치며, 콜로이드 실리카 양이 30 g인 경우에 $37^{\circ}$의 가장 낮은 접촉각과 H의 우수한 연필경도를 나타내었다.
