Abstract
The molecular arrangements near solid surfaces and in narrow slits of liquid tridecane, containing 5 wt.-% of a diluent having the size and the interactions of a methylene group, have been studied by atomistic computer simulations using the Monte Carlo technique. The presence of the diluent does not modify the tendency to form segmental layers near the solid surfaces. However, the diluent is preferentially adsorbed a t these surfaces, replacing part of the chain ends. As a result, the o rdered structures with nearly two-dimensional chains found for the pur e liquid in analogous conditions are partly destroyed.
