Observation of contact angle hysteresis due to inhomogeneous electric fields
Wetting of surfaces can be affected by surface roughness, presence of surface chemical defects, or by electric fields. Here, the authors perform electrowetting experiments on microstriped electrodes and show that the droplet’s static contact angle hysteresis can be controlled by an inhomogeneous ele...

Summary: | Wetting of surfaces can be affected by surface roughness, presence of surface chemical defects, or by electric fields. Here, the authors perform electrowetting experiments on microstriped electrodes and show that the droplet’s static contact angle hysteresis can be controlled by an inhomogeneous electric field while remaining isotropic, as does the droplet contact radius. |
