A method for the determination of the acid-base interactions and the work of adhesion at a solid-liquid interface

摘要: A new method for determination of the work adhesion at a solid-liquid interface is described in this paper. The based on ideas Fowkes, who showed that total WSI could be reduced to two kinds interactions, namely, due dispersion or London forces, and non-dispersion acid-base interactions: makes use classical contact angle technique (sessile drop Wilhelmy method). novel feature our approach WSL using aqueous acidic basic solutions as test liquids pH range from 1 14. By procedure, well-defined complexes between functional groups surface solid varying value can formed. As consequence, different values are obtained, which derived enthalpy specific their concentration:
