The ability of a liquid to spread over a solid surface.

Surface Tension: Surface tension is the attractive force between the molecules in a liquid's surface layer. It is a crucial metric in understanding wetting and surface chemistry, as it determines how easily a liquid will spread over a surface.
Contact Angle: Contact angle is the angle between a liquid droplet and the surface it rests upon. The angle gives an indication of the intermolecular interaction between the liquid and the surface. It is a critical parameter in the study of wetting phenomena.
Adhesion: Adhesion refers to the attraction between two different substances, such as a liquid and a solid. It plays a crucial role in determining the wetting behavior of a liquid on a surface.
Cohesion: Cohesion refers to the attraction between molecules of the same substance. It plays a crucial role in determining the surface tension and wettability of a liquid.
Hydrophobicity and Hydrophilicity: Hydrophobicity is the property of a material that repels water, while hydrophilicity is the property of a material that attracts water. Understanding these properties is essential in understanding wetting phenomena.
Surfactants: Surfactants are compounds that lower the surface tension of a liquid. They play a crucial role in detergents, emulsions, and wetting agents.
Wetting Agents: Wetting agents are compounds that reduce the contact angle between a liquid and a surface, allowing the liquid to spread more easily. They are used in many industries, including agriculture, paint, and textile production.
Capillary Action: Capillary action refers to the tendency of a liquid to rise in a narrow tube due to adhesion and cohesion. It is critical in many natural and synthetic systems, and understanding capillary action is essential in understanding the behavior of liquids on surfaces.
Surface Free Energy: Surface free energy is the amount of energy required to create a unit area of a surface. It plays a critical role in determining wetting behavior and is affected by factors such as surface roughness, chemistry, and temperature.
Wetting Hysteresis: Wetting hysteresis refers to the difference in contact angles when a liquid is advancing versus receding on a surface. It is an essential parameter in many practical applications, such as inkjet printing and coating processes.
Spreading: The ability of a liquid to spread over a solid surface.
Wetting: The process of a liquid forming a film over a solid surface.
Non-wetting: The inability of a liquid to spread or wet a solid surface.
Partial wetting: A situation where a liquid wets partially on a solid surface and forms a contact angle.
Dynamic wetting: A process where a liquid wets and spreads over the surface while undergoing a change in contact angle.
Equilibrium wetting: A state where the contact angle remains constant, indicating a stable wetting condition.
Capillary wetting: The process where a liquid rises in a narrow tube or porous medium due to the force of capillary action.
Superwetting: A wetting condition where the contact angle is close to zero, and the liquid spreads over the solid surface completely.
Ultrawetting: A wetting condition where the liquid spreads over the solid surface not only completely but even enters the surface structure of the solid.
Non-equilibrium wetting: A state where the contact angle is not constant, indicating an unstable wetting condition.
"Wetting is the ability of a liquid to maintain contact with a solid surface, resulting from intermolecular interactions when the two are brought together."
"The degree of wetting (wettability) is determined by a force balance between adhesive and cohesive forces."
"Wetting is important in the bonding or adherence of two materials."
"There are two types of wetting: non-reactive wetting and reactive wetting."
"Wetting deals with three phases of matter: gas, liquid, and solid."
"It is now a center of attention in nanotechnology and nanoscience studies due to the advent of many nanomaterials in the past two decades (e.g. graphene, carbon nanotube, boron nitride nanomesh)."

"Wetting and the surface forces that control wetting are also responsible for other related effects, including capillary effects."
"This happens in presence of a gaseous phase or another liquid phase not miscible with the first one."
