Mesoporous silica films with cylindrical pores oriented normal to the substrate are prepared by selective deposition of silica within the poly(hydroxy styrene) domains of poly(-methyl styrene-b- hydroxy styrene) template films using supercritical carbon dioxide as a delivery medium. Atomic force microscopy, electron microscopy, and grazing incidence small angle X-ray scattering (see figure) studies confirm the vertical alignment of the cylindrical pores.
