论文摘要
具有可切换性润湿性的基材的发展是快速的。开关频率和基材状态之间的接触角差的极限被稳定地推动。我们研究了液滴在均匀基板上的行为，该底物在两个潮湿之间进行切换，以实现各种开关频率。在这里，我们对润湿行为对开关频率的依赖特别感兴趣。我们表明，通过分子动力学模拟在粒子水平上获得的结果和通过薄膜模型在连续级别上获得的结果是一致的。简单模型作为润湿分子理论（MKT）和基于MKT的分析计算的预测也显示出良好的一致性，并提供了对潜在机制的更深入的见解。
The development of substrates with a switchable wettability is on a fast pace. The limit of switching frequencies and contact angle differences between substrate states are steadily pushed further. We investigate the behavior of a droplet on a homogeneous substrate, which is switched between two wettabilities for a large range of switching frequencies. Here, we are particularly interested in the dependence of the wetting behavior on the switching frequency. We show, that results obtained on the particle level via molecular dynamics simulations and on the continuum level via the thin-film model are consistent. Predictions of simple models as the molecular theory of wetting (MKT) and analytical calculations based on the MKT also show good agreement and offer deeper insights into the underlying mechanisms.
