Miktoarm Architecture Effect on the Phase Behavior Characteristics of PS-b-PLA Block Copolymer |
| 초록 |
Block copolymer (BCPs) are widely used in materials science due to their ability to be self-assembled into nanostructures. Recent advances in BCPs focused on the development of new systems that can overcome the size limitation of traditional BCPs. Such efforts have been demonstrated with design and synthesis of new type of BCPs having high interaction parameter (χ). Although many previous studies have been mainly focused on linear BCPs, it was also suggested that non-linear architecture such as star BCPs can further promote the phase segregation. Herein we synthesized well-defined miktoarm PS-b-PLA BCPs to compare the segregation behavior with linear PS-b-PLA BCPs having similar molecular weights and volume fraction. As a control sample, linear PS-b-PLA BCPs of similar volumetric ratio were synthesized. The samples were thermally annealed in thin film and bulk state, and characterized with SEM, TEM, and SAXS. These phase separation behaviors were also compared with SCFT simulation. |
