摘要：

The Lifskitz-van der Waals/acid-base approach proposed by van Oss et al. is found to yield inconsistent solid surface tensions and components from contact angles, for fluorocarbon, polystyrene, and poly(methyl methacrylate) solid surfaces. It is also shown that the approach cannot predict the correct interfacial tensions of all liquid-liquid pairs in question: the predicted interfacial tensions range from 34% lower to 112% higher than the experimental values. Thus, the usefulness of the approach for surface tension components and interfacial tensions is open to question. The liquid surface tension components postulated since 1986 are also summarized.
