Self-Assembled Morphologies of Lamella-Forming Block Copolymers Confined in Conical Nanopores

Block copolymers (BCPs) under nanoscale confinement can self-assemble to form novel nanostructures that are not available in the bulk state. Particularly, the ordering process of block copolymers and the resulting morphologies depend sensitively on the dimensionality, geometry, and surface property of the confining environment. In this study, we report on the self-assembled morphologies of polystyrene-block-1,4-polybutadiene (PS-b-PB) confined …
