Abstract
A density functional approach is used to study adsorption and phasebehaviour of the two-bonding-site associating Lennard-Jones (LJ)fluid in slit-like pores with energetically heterogeneous walls.Phase behaviour of strongly and weakly associating, polymerizingfluid in the pores with a periodic surface potential, characterizedby different strengths and the spacings between adjacent minima, aswell as different pore widths is discussed. A comparison of theresults obtained for strongly and weakly associating fluidselucidates the role of bonding between fluid species in thepore-filling mechanism. An interplay between layering transitions,the formation of an intermediate `bridge' phase and the finalcapillary condensation in the pores with energetically corrugatedwalls is discussed in detail.
