摘要：

A hexagonal web of carboxylic-terminated nanostripes (left image, bright areas) is patterned onto a methyl-terminated surface of an octadecyltrichlorosilane monolayer. A thermally annealed polystyrene-block-poly(ethylene oxide) (PS-b-PEO) thin-film, spin-cast on the chemical pattern (right image), exhibits surface normal oriented cylindrical PEO microdomains on the methyl-terminated regions only. These chemical patterns effectively template the order and spatial orientation of diblock-copolymer microdomains.
