Caption

To investigate the wetting of the surface and apply the voltage at the same time, an instrument was built specially for this purpose, in which a liquid drop is brought on the surface through a very thin glass tube. The drop is made bigger and smaller while at the same time its shape is recorded. Whether the drop shape is flat or more rounded depends on the properties of the surface.
