The structure of a sticky interface

Sticky interface properties are studied. The influence of bulk dimerization on the density profile and adsorption coefficient is investigated using the associative version of the Henderson-Abraham-Barker equation. It is shown that the dimerization process in the interfacial region can be treated as a second adsorbed layer formation. It is also shown that beyond the second adsorbed layer the structure of the system is similar to the hard-wall case.
