Abstract

Monte Carlo simulations of idealized models of polymer chains at interfaces were carried out. The models chains consisted of hydrophobic and hydrophilic united atoms (beads) and were embedded in a [310] hybrid lattice. The polymer beads interacted through a long‐distance contact potential and were placed near an impenetrable and attractive surface. The properties of the model system were determined using the replica‐exchange Monte Carlo algorithm. The influence of temperature, adsorption strength and bead sequence on the properties of model chains were studied. It was shown that weak chain adsorption did not change alter the process of chain collapse significantly. For strong adsorption, the chain rearrangements were found to be more complicated, especially for alternating copolymers.
