Abstract
We study the problem of adsorption of polymer chains in a system
containing two impenetrable attracting interfaces within the mean-field
approximation. We find the exact solution of this mean-field polymer
adsorption problem that is controlled by a single scaling variable describing
the coupling between the impenetrable interfaces due to the polymer chains.
At the saturation point we obtain the total number of adsorbed monomers, the
total energy of the system and the force acting between impenetrable
interfaces that is turned to be strictly attractive and monotonously decaying
towards zero for increasing distance between the interfaces.
