[摘要]：We report the self-assembly of organic-inorganic block copolymers (BCP) in thin-films by simple solvent annealing on unmodified substrates. The resulting vertically oriented lamellae and cylinders are converted to a hard silica mask by single-step, highly selective oxygen plasma etching. The size of the resulting nanostructures in the case of cylinders is less than 10 nm.
