The surface free energy of a solid/iiquid interface can be described as a function of individual force components of the solid and liquid. For the relationship, the following equation, which was assumed by Owens and Wendt [21], is most reliable for polymeric solids ... [Pg.192]

Here oth is the fraction of thermal expansion connected with changes in hole concentration (free-volume expansion), ), is the energy of hole formation, r=M/p0 Vn Na, where NA is the Avogadro number,M molecular weight, p0 the density of a liquid without holes at absolute zero, and Vn the hole volume. For polymeric systems r is very small, and then ahTis the function of E IRTalone. The value Of, is identified with experimentally observed changes in the thermal expansion coefficients A a at Tg, i.e. [Pg.81]
