Experimental verification of certain van Oss - Good method elements
Polimery 1999, No 3, 212
Theoretical principles of a new van Oss—Good method for measuring free surface energy of polymers are presented with reference to the Owens—Wendt method. Other aspects including the Lewis theory of acids and bases and hydrogen bonds are discussed. Basic liquids used in Oss—Good method-based measurements are described. An activated polypropylene film was used to verify the hypothesis of equivalent use of various nonpolar liquids (diiodomethane and a-bromonaphthalene) and two procedures are described for determining the (acidic and basic) components of the free surface energy [eqn. (13) or (14)]. Tire equivalence  claimed was not confirmed by present results (Table 3, Fig. 1). In the case of the activated PP film, eqns. (13) and (14) gave nearly identical values of the free surface energy.
