interfacial adhesion
Adhesion in which interfaces between phases or components are maintained by @[email protected] forces, chain entanglements, or both, across the interfaces.
  1. Interfacial adhesion is also referred to as tack.
  2. Adhesive strength (recommended symbol: \(F_{\text{a}}\), unit: \(\text{N m}^{-2}\)) 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: \(\gamma\), unit: \(\text{N m}^{-1}\), \(\text{J m}^{-2}\)) 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.
