We fabricated stacked structures by using lamellar-forming Polystyrene-block-Poly(methyl methacrylate) (PS-b-PMMA). When cylindrical cavities made by anodic aluminum oxide (AAO) template are modified by thin brush layers of PS-ran-PMMA copolymer, PS and PMMA lamellae are stacked alternatively. After removal of AAO template, followed by silver deposition on PS microdomains by using thermal evaporation, high density array of stacked lamellae with silver nanoparticle shows very interesting optical properties. Namely, the absorption of visible (or near Infra-red) light depends significantly on irradiation angle.
