I. Preface
Nanomaterial science and engineering has become a global research hotspot. When studying the surface modification of nanomaterials, the concept of contact angle often comes into play. The contact angle refers to the angle formed by the tangents to the gas-liquid and solid-liquid interfaces at the three-phase boundary point of a liquid drop on a solid horizontal surface, which encloses the liquid phase.
Surface energy is a measure of the energy required to disrupt intermolecular chemical bonds during the creation of a material's surface. In solid-state physics, surface atoms have more energy than those within the material, causing them to spontaneously tend towards the interior rather than the surface. Another definition of surface energy is the additional energy that exists at the material's surface compared to its interior.
The force of attraction between any two adjacent parts of a liquid surface, perpendicular to their unit length boundary lines. The formation of surface tension is closely related to the special stress state of molecules within the thin layer of the liquid surface. The existence of surface tension gives rise to a series of special phenomena observable in everyday life.
