Abstract
<p>Antifouling surfaces are required for medical equipment, food containers, and exterior walls. In order to realize the antifouling surfaces, it is necessary to improve droplet sliding efficiency. In this study, we measured the interfacial resistance and sliding velocity of a droplet on the slope of a silicone film. A contact angle measuring device (First Ten Angstroms, Inc: FTA1000) was used. The interfacial resistance was proportional to the power of the sliding velocity. The effect of viscous force on interfacial resistance was smaller than that of surface tension. To consider the relationship between surface tension and viscous force, we calculated the Laplace pressure of the droplet, which is dependent on the droplet shape. Laplace pressure was positively correlated with viscous force, which suggests that droplet shape is determined by surface tension and viscous force.</p>
