Contact electrification (also known as triboelectricity) is a phenomenon that can occur at the interface between two materials. It means that the materials become electrically charged when they come into contact with each other. A well-known, everyday example of contact electrification is when your hair sticks out in all directions after rubbing it against a balloon.
In a recent journal article by Tang et al., the researchers investigated the relationship between electric charge density and wettability behaviour at a solid-liquid interface after contact electrification. The study looked at 24 different materials in total and found a linear relationship between charge density and wettability.

In this study, static and dynamic contact angles were measured using the sessile drop and needle-in-drop method, respectively, in order to gain insights into the wetting behaviour. To do so, the researchers used our OCA25 contact angle meter.
