File Name: relation between surface tension and surface energy .zip
Surface free energy can be considered as the surface tension of a solid. Surface free energy, or SFE for short, arises from the molecular interactions at the air — solid interface. Surface free energy is important in many application areas. It dictates how the solid behaves when put in contact with liquids. The surface free energy of a solid predicts how a material behaves when placed in a human body or how a coating formulation spreads on it.
Schramm, Laurier L. Saskatchewan Research Council, Saskatchewan, Canada. Last reviewed: June The force acting in the surface of a liquid, tending to minimize the area of the surface. Surface forces, or more generally, interfacial forces, govern such phenomena as the wetting or nonwetting of solids by liquids, the capillary rise of liquids in fine tubes and wicks, and the curvature of free-liquid surfaces Fig. The surface tensions of liquids have important influences in many phenomena occurring in industrial processes and in everyday life.

The wettability of droplets on a low surface energy solid is evaluated experimentally and theoretically. Water-ethanol binary mixture drops of several volumes are used. In the experiment, the droplet radius, height, and contact angle are measured.
Surface Energy. Surfaces have energy associated with them because work is needed to form them. Surface energy is the work per unit area done by the force that creates the new surface. Material Surface Energy J.
Surface free energy or interfacial free energy or surface energy quantifies the disruption of intermolecular bonds that occurs when a surface is created.
