In surface science, surface energy (also interfacial free energy or surface free energy) quantifies the disruption of intermolecular bonds that occurs when a surface is created.
A key quantity that is connected with the chemistry of all surfaces is the surface energy. This is the (thermodynamically unfavorable) energy of making "dangling bonds" at the surface. Atoms at the surface are under-coordinated, and because breaking bonds costs energy, surface atoms always have higher energy than atoms in the bulk.
Definition. Surface energy is the excess energy at the surface of a material compared to its bulk, arising from the disruption of intermolecular bonds at the surface. It plays a crucial role in determining the behavior of small systems and nanomaterials, influencing phenomena such as wetting, adhesion, and stability of colloids and nanoparticles.
Surface energy is a measure of the excess energy at the surface of a material compared to its bulk. It plays a crucial role in determining how liquids spread on solids, influencing adhesion and coating properties, and is vital for the performance of coatings and adhesives.
Surface energy represents the additional energy required to create a new surface by breaking intermolecular bonds. This imbalance leads to surface tension, which manifests as a force acting along the liquid's surface.
It is defined as the energy required to increase the surface area of a unit of a material. This term is used in various fields such as chemistry, physics, materials science and surface technology. Surface energy is closely linked to the wettability of surfaces.
