We fabricated high density array of stacked lamellae by confinement of symmetric polystyrene-block-poly(methyl methacrylate) copolymer (PS-b-PMMA) into cylindrical pores derived from anodic aluminum oxide (AAO) template. The wall of AAO was modified by thin brush layer of PS-ran-PMMA copolymer. When the silver was selectively deposited on PS microdomains, we obtained high density array of silver striped nanorods. Very interestingly, UV-visible spectra of silver striped nanorods showed different peaks depending on incident angle of a laser. Finally, spiral structure was prepared by increasing confinement, that is, top surface of cylindrical AAO was covered by homopolymer. |
