| 中文摘要 | the self-assembly of symmetric coil-rod-coil aba-type triblock copolymer melts is studied by applying self-consistent field lattice techniques in a three-dimensional space. the self-assembled ordered structures differ significantly with the variation of the volume fraction of the rod component, which include lamellar, wave lamellar, gyroid, perforated lamellar, cylindrical, and spherical-like phases. to understand the physical essence of these phases and the regimes of occurrence, we construct the phase diagram, which matches qualitatively with the existing experimental results. compared with the coil-rod ab diblock copolymer, our results revealed that the interfacial grafting density of the separating rod and coil segments shows important influence on the self-assembly behaviors of symmetric coil-rod-coil aba triblock copolymer melts. we found that the order-disorder transition point changes from f(rod)=0.5 for ab diblock copolymers to f(rod)=0.6 for aba triblock copolymers. our results also show that the spherical-like and cylindrical phases occupy most of the region in the phase diagram, and the lamellar phase is found stable only at the high volume fraction of the rod. |
