摘要
This study investigated the behavior of water and oil droplets formed on a pillar structured surface by performing molecular dynamics simulations. The effects of the pillar height on the behavior of water and oil droplets were studied. Their qualitative and quantitative behavior of water were analyzed and compared based on the droplet shape, contact angle, and surface characteristic energy.
