✦ Synopsis

The wetting behavior of Lennard-Jones associating fluid on a crystalline surface is studied using Monte Carlo simulation in the isobaric-isothermal ensemble. We explore the structure of the adsorbed film, characterized by the distribution of all particles and the distributions of centers of mass of dimers, as well as by orientational distributions of the dimers. The simulations performed indicate the existence of a prewetting-like behavior of the adsorption isotherm. The results for a crystalline surface are compared with simular results obtained for a structureless surface. Finally, we present some density functional theory evaluations and compare them with the simulation results at a high temperature. Copyright 2000 Academic Press.

In the present letter, we study the role of hydrogen bonds on the density of a pure, associating liquid in the solid-liquid interfacial region. The approach followed by us is to treat the liquid phase as comprising (i) oligomers/clusters of various sizes formed between the molecules of associating c
