제목 Line Patterns of Block copolymers with Large Periods Exceeding 100 nm
초록 Block copolymer nanostructures with large periods exceeding 100 nm remains challenging, because the translational ordering of long-chained block copolymer is hindered by its very low chain mobility. Here, rapid evolution of a perpendicularly oriented lamellar morphology in high-molecular-weight block copolymer films on a neutral substrate is demonstrated using a neutral-solvent-vapor annealing process, which was sequentially combined with a thermal annealing process. The great synergy with the topographically patterned substrate facilitated unidirectionally structural development of ultrahigh-molecular-weight block copolymer thin films—even for the structures with a large period of 200 nm—leading to perfectly guided, parallel, and highly ordered line-arrays of perpendicularly oriented lamellae in the trenches.
