interfacial adhesion

https://doi.org/10.1351/goldbook.IT07253
Adhesion in which interfaces between phases or components are maintained by intermolecular forces, chain entanglements, or both, across the interfaces.
Notes:
  1. Interfacial adhesion is also referred to as tack.
  2. Adhesive strength (recommended symbol: Fa, unit: N m-2) is the force required to separate one condensed @[email protected] from another at the @[email protected] between the two phase domains divided by the area of the @[email protected]
  3. @[email protected] (recommended symbol: γ, unit: N m-1, J m-2) is the change in Gibbs energy per unit change in interfacial area for substances in physical contact.
  4. Use of the term interfacial energy for @[email protected] is not recommended.
