Figure 3

Representative SEM images of the templates and the replicated structures. (A) An AAO template with hexagonal arranged pores within each domain. The inset shows a zoom-in image of the AAO pore structure. (B) Standing PMMA nanoposts after templating AAO. The inset shows the separation of the nanoposts. (C) A template of 3D packed silica beads with PS filling the interstitial space. (D) A network of PS porous structure after silica bead removal. Scale bars in (A) – (D) are 5 μm and scale bars in the insets are 1 μm.
