In the following, we assume that the confining walls of the container or the supporting substrate (e.g., a wafer) are hard and non-deformable, that is, the properties of the solid do not change as it is brought into contact with the polymer material. If one measures the density profile of the polymer material at the polymer-solid contact, one will typically observe a steep rise of the density from zero (in the solid, confining wall) to the bulk density of the polymer material. The spatial extension of this polymer-solid interface is only a few ingstrom, that is, its width is dictated by the size of the atomistic constituents. On the other hand, in multicomponent polymer materials (i.e., polymer blends or polymer-solvent mixtures) one component vhll enrich at the solid surface, and the width of these enrichment layers may extend far away from the solid surface. 

In both situations the polymer-solid interface is much thinner than the width of the enrichment layer or the interphase. Since previous sections have dealt with phase coexistence in multicomponent polymer materials, we restrict ourselves to the wetting phenomena (2) and refer the reader to References [115-117] for simulation studies of adsorption phenomena within the framework of coarsegrained models.
