Expérimental Description
Triboelectric charging - the process by which dielectric surfaces can acquire a net charge when rubbed together - represents a fundamentally misunderstood process in physics, with both fundamental and mundane consequences. The idea of this internship is to focus on the particular case of liquid triboelectrification, whereby water drops sliding on hydrophobic surfaces leads to a macroscopic separation of charges. In particular, we will employ recently developped surface charge mapping strategies to probe the peculiar dynamics of the ions trapped at the solid/gaz interface following liquid tribocharging.
