Adhesion in which interfaces between phases or components are maintained by @I03098@ forces, chain entanglements, or both, across the interfaces.
Notes:
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 @PT07286@ from another at the @I03082@ between the two phase domains divided by the area of the @I03082@.
3. @I03088-1@ (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 @I03088-2@ is not recommended.
