The effects of surface curvature on the adsorption of surfactants at the solid-liquid interface.
The adsorption of surfactants from dilute oil solutions on to solid surfaces is studied as a function of surface curvature and surface coverage. Coarse-grained molecular models, computer simulations, and umbrella sampling are used to compute the dependence of the free energy of adsorption on to a spherical colloid surface with radius R. It is shown that for fixed surface coverage, and with all ...

متن کاملAdsorption and surface-induced self-assembly of surfactants at the solid]aqueous interface
Increasing insight into the interfacial behaviour of surfactants has emerged during the past few years. Important advances in this area are largely due to the use of surface-specific techniques like ellipsometry, neutron reflectivity, fluorescence Ž . spectroscopy, and atomic force microscopy AFM for in situ studies of surfactant layer properties. This review covers recent developments in the a...
متن کاملThermodynamics of adsorption of surfactants at solid-liquid interface
Adsorption of surfactants at interfaces is detenIlined by a number of forces involving electrostatic attraction, covalent bonding, hydrogen bonding, hydrophobic bonding and solvation and desolvation of various species. The extent and type of forces involved vary depending on the adsorbate and the adsorbent and also the composition and other characteristics of the solvent and dissolved component...
متن کاملStudies on the Adsorption of Surfactants and Polymers to Surfaces and Their Effects on Colloidal Forces
Surfactants, polymers, and their mixtures are widely used in commercial formulations of paints, water-based adhesives, detergents, food, and other products. This thesis describes measurements of the forces acting on colloidal particles in surfactant and polymer solutions. The change in force on addition of surfactants and polymers is usually caused by adsorption to an interface. In this thesis,...
