Self-exchange, adsorbed polymer layers

Self-exchange of homopolymers has also been studied with Monte Carlo simulations [25]. One interesting result emerging from these simulations is that adsorbed layers of homopolymers, when exposed to a solution of the same polymers, can readily exchange attaehed molecules against free ones. However, not all molecules participate equally in this exchange process. There appears to be a relation... 

A logical division is made for the adsorption of nonelectrolytes according to whether they are in dilute or concentrated solution. In dilute solutions, the treatment is very similar to that for gas adsorption, whereas in concentrated binary mixtures the role of the solvent becomes more explicit. An important class of adsorbed materials, self-assembling monolayers, are briefly reviewed along with an overview of the essential features of polymer adsorption. The adsorption of electrolytes is treated briefly, mainly in terms of the exchange of components in an electrical double layer.
