摘要
滑电效应是滑动液滴与表面之间自发产生的电荷分离现象。此处,我们从三相接触线处产生的电压角度描述该效应。该电压在电容器之间移动电荷,其中一个电容器由液滴形成,另一个在表面上形成。通过引入遇水接触时电压的自适应机制,我们可以对多种表面上的液滴带电实验进行建模,包括具有依赖于液滴速率的电荷极性的更特殊表面。因此,自适应双电容模型能够针对电荷分离机制的分子细节提供新的见解。

备注
The experimental results are accurate, but the physical model proposed in the paper does not fully capture the underlying physics behind the data. We are actively working to develop an improved model that better describes the experimental observations
