Attachment of interfaces between phases or components that is maintained by intermolecular forces, chain entanglements, or both.
Notes:
- Interfacial adhesion is also referred to as tack.
- Adhesive strength (recommended symbol: \(F_{\rm{a}}\), unit: \(\pu{N m^{-2}}\)) 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: \(\upgamma\), unit: \(\pu{N m^{-1}}\), \(\pu{J m^{-2}}\)) is the change in Gibbs energy per unit change in interfacial area for substances in physical contact.
