论文摘要
滑动电气化是表面和滑动滴之间的自发电荷分离。在这里，我们用在三相接触线上产生的电压来描述这种效果。该电压在电容器之间移动电荷，该电压是由液滴形成的，一个在表面上。通过在水接触时引入电压的适应，我们可以在许多表面上对掉落电荷实验进行建模，其中包括具有降率依赖性电荷极性的外来电荷。因此，自适应两个电容器模型可以对电荷分离机理的分子细节进行新的见解。
Slide electrification is a spontaneous charge separation between a surface and a sliding drop. Here, we describe this effect in terms of a voltage generated at the three-phase contact line. This voltage moves charges between capacitors, one formed by the drop and one on the surface. By introducing an adaptation of the voltage upon water contact, we can model drop charge experiments on many surfaces, including more exotic ones with drop-rate dependent charge polarity. Thus, the adaptive two capacitor model enables new insights into the molecular details of the charge separation mechanism.
