One-to-one insertion of sphere within curved domain by using host-guest self-assembly of block copolymers blends |
| 초록 |
Block copolymers(BCPs) have been regarded as attractive material for uniform nanostructures with excellent functionalities due to their ability to self-assemble into variety of nanostructures. However, extension of their geometric variability is not straightforward due to their limited thin film morphologies. Here, we report that unusual and positioning between host-guest BCP microdomains from BCP blends. Hybrid self-consistent field theory(HSCFT) simulation theoretically supports that the precise registration of a spherical BCP microdomain (guest, B-b-C) at the center of perforated lamellar BCP nanostructure (host, A-b-B) can energetically stabilize the blended morphology. Furthermore, we also blended BCPs and nanoparticles(NPs) to realize the delicate insertion of NPs within the curved domains of BCPs. Our results suggest the possibility of a new pathway to construct more diverse and complex nanostructures with large scalability using controlled blending of various BCPs and NPs. |
