Abstract

The adsorption of macromolecules at solid/solution interfaces differs in several respects from that of small molecules. Some of these differences are reflected in the adsorption isotherm (Figure 1). Region A corresponds to isolated adsorbed macromolecules, adsorbed in a tail/loop/train configuration (Figure 2). This minimum free energy situation depends on the balance between the net changes in potential energy (ΔU) and entropy (ΔS) associated with the adsorption process. ΔU reflects changes in the number of segment/surface, solvent/surface and segment/solvent contacts; ΔS reflects not only changes in the configurational entropy of the adsorbed polymer concerned, but also changes in the thermal entropy of the adsorbed polymer and desorbed (or released) solvent molecules.
