A general route to fabricate highly ordered arrays of nanoscopic silicon oxide dots and stripes (see figure) from block copolymer thin films is described. Poly(styrene-b-4-vinylpyridine) thin films with cylindrical microdomains oriented normal and parallel to the surface were used as templates for the fabrication of nanoscopic silicon oxide, with polydimethylsiloxane as the inorganic precursor.
