Adhesion in which interfaces between phases or components are maintained by intermolecular forces, chain entanglements, or both, across the interfaces.
Notes:
- Interfacial adhesion is also referred to as tack.
- Adhesive strength (recommended symbol: \(F_{\rm{a}}\), unit: \(\rm{N m}^{-2}\)) is the force required to separate one condensed phase domain from another at the interface between the two phase domains divided by the area of the interface.
- Interfacial tension (recommended symbol: \(\gamma\), unit: \(\rm{N m}^{-1}\), \(\pu{J m-2}\)) is the change in Gibbs energy per unit change in interfacial area for substances in physical contact.
- Use of the term interfacial energy for interfacial tension is not recommended.
