 Adhesion

Attraction between different contacting surfaces. Adhesion can be described by interfacial work per area, while a measured pull-off force additionally depends on geometry and the elastic response.

Adhesion refers to the tendency of different surfaces or substances to cling to each other. It is a physical phenomenon that occurs at the interface between two materials, where intermolecular forces between molecules of different substances cause them to stick together. Adhesion is important in a variety of fields, including materials science, biology, and engineering.
