Surface interaction refers to the way different materials come into contact and affect each other at their boundaries. This can involve physical forces, chemical reactions, or energy transfer. For example, when water interacts with a glass surface, it can create a thin film due to adhesion, which influences how the water behaves.
In various fields, such as materials science and nanotechnology, understanding surface interactions is crucial. These interactions can determine properties like friction, wetting, and adhesion, impacting everything from the performance of coatings to the effectiveness of adhesives.
