Nanoscopic confinement of block copolymers (BCPs) offers a promising means to manipulate nontraditional morphologies completely different from their bulk morphologies. Many research groups have studied confinement effect on BCP morphologies. While most of them have focused on BCPs morphology confined in circular space (i.e., cylinder, sphere), very few studies have been done for the BCP morphologies confined in other types of geometries such as square. Here, we investigated the confined morphology of block copolymer inside the square channel prepared by anodized aluminum oxide (AAO). Based on the theoretical studies, we expect new BCP morphologies that is not observed inside circular space through the square confinement. Especially, if we use selective brush to modify AAO surface, more interesting morphologies such as U, S shaped-nanostructures that is applied to plasmonics can be obtained by surface selectivity.
