| 中文摘要 | by using a combinatorial screening method based on the self-consistent field theory, we investigate the equilibrium morphologies of linear abcba and h-shaped (ab)(2)c(ba)(2) block copolymers in two dimensions. the triangle phase diagrams of both block copolymers are constructed by systematically varying the volume fractions of blocks a, b, and c. in this study, the interaction energies between species a, b, and c are set to be equal. four different equilibrium morphologies are identified, i.e., the lamellar phase (lam), the hexagonal lattice phase (hex), the core-shell hexagonal lattice phase (csh), and the two interpenetrating tetragonal lattice phase (tet2). for the linear abcba block copolymer, the reflection symmetry is observed in the phase diagram except for some special grid points, and most of grid points are occupied by lam morphology. however, for the h-shaped (ab)(2)c(ba)(2) block copolymer, most of the grid points in the triangle phase diagram are occupied by csh morphology, which is ascribed to the different chain architectures of the two block copolymers. these results may help in the design of block copolymers with different microstructures. |
