주기적 줄무늬 구조물 위의 물 액적에 관한 연구

다국어 초록 (Multilingual Abstract)

We investigated the variation in contact angle of a nano-sized water droplet on a nano stripe-patterned surface using molecular dynamics simulation. By changing the height and width of the stripe pillar, and the gap width of the stripes, we observed the contact angle of water droplet in equilibrium. When the surface energies were 0.1 and 0.3 ㎉/㏖, the calculated contact angles were in good agreement with the Cassie and Baxter equation. However, when the surface energy is 0.5 ㎉/㏖, the contact angles are observed to be perturbed along the Cassie and Baxter equation.
