Abstract
Free energies and density profiles of the diblock copolymers near patterned surfaces were analyzed. A Gaussian chain model and density-functional self-consistent-field theory was used to to study a random mixing approximation for nonbonded interactions and bonding constraints. It was observed that density functional profiles can be obtained by complex roots of a sixth-degree polynomial. The results show that lamellar ordering appears near the surface above the order-disorder transition.
