| 논문초록 | Directed self-assembly (DSA) using high-molecular-weight (HMW) block copolymer (BCP) has been a challenging issue because of the difficulty in polymer synthesis and restricted chain mobility. To overcome such barriers, we successfully synthesized HMW BCPs by living anionic polymerization and fabricated nanostructures with period of 100 – 200 nm by solvent vapor annealing (SVA). The resulting morphologies show diversity from 2-dimensional lamellae and hexagonally-packed cylinders to 3-dimensional gyroid network structures and the orientation was controlled by graphoepitaxy and surface modification techniques. Finally, the long-range ordered patterns showed diverse applicabilities to photolithography, enhanced ultrafiltration membrane, pattern transfer and next-generation optical metamaterials, etc.. |
