| Résumé : |
Currently, there is no satisfactory molecular theory allowing for the prediction of the interaction of two materials across their mutual interface. All existing theories assume there is a part of the molecular interactions involved that obeys the London inverse-sixth power law, as is valid for the separations encountered in gases. It is shown that, just as the London law is no longer valid in the Casimir limit of large separations, so it is also invalid in the limit of close molecular contact encountered in condensed phases. The experimental data on molecular interactions is reviewed. The Szyszkowski formalism is developed, and shown to explain the temperature dependence observed by Vrbanac and Berg. The formula of van Oss, Good and Chaudhury is shown to be valid under certain simplifying assumptions, but in order to develop it into a theory with significant predictive strength, it must be modified in three aspects : by the use of an additional parameter ; by non-linearity ; and by separate consideration of entropic terms. |
