Abstract
The conventionally used Modified Self-consistent Field Theory (MSCFT) for confined system is known to have two major difficulties: numerical instability and dependence on artificial constraints. Here we use Compressible Model based Self-consistent Field Theory (CMSCFT), which has no artificial constraints, and furthermore overcomes numerical instability problems. CMSCFT asymptotically converges to the conventional Self-consistent Field Theory (SCFT) as the compressibility tends to zero. Satisfactory simulations on some hard-surface confinements, focusing on one-dimensional situation, are also given. We suggest that CMSCFT will be a promising tool for copolymer systems with hard surface confinements.
