Ordered microstructures self-assembled from A2m+1BmCm comblike copolymers

Using self-consistent field theory, we investigate the ordered microstructures self-assembled from A _2m + 1 B _m C _m comblike copolymers. We find that the architectures, volume fractions of the components and the interaction parameters dramatically influence the phase behavior. By systematically changing above factors, we obtain six kinds of regular structures. They are hexagonal lattice phase, two interpenetrating tetragonal lattice, core shell hexagonal lattice phase, two-phase lamellar structure, hexagonal phase with beads inside and three-phase lamellar structure. Further we construct the phase diagrams to clarify the phase regions where the different microstructures exist. The results may be helpful in the design of the desired microstructures.
