Abstract
A monomer-resolved Density Functional Theory study is performed to analyze the interfacial behavior of semiflexible polymers under variable solvent conditions, either in contact with a planar attractive wall or confined in a planar slit formed by two attractive walls. The study focuses on the effects of chain length and persistence length on the wetting transition at a wall and capillary condensation in a slit. The wetting temperature predicted by DFT is found to increase monotonically with the chain stiffness, in agreement with the major trends observed in simulation studies. The DFT results for the capillary condensation in a planar slit are compared to the predictions of the Kelvin equation.
