  text: Micropatterned nanoporous aluminum oxide arrays are prepared on silicon wafer
    substrates by using photopolymerized poly(dimethylacrylamide) hydrogels as porogenic
    matrices. Hydrogel micropatterns are fabricated by spreading the prepolymer mixture
    on the substrate, followed by UV photopolymerization through a micropatterned
    mask. The hydrogel is covalently bonded to the substrate surface. Al2O3 is produced
    by swelling the hydrogel in a saturated aluminum nitrate solution and subsequent
    thermal conversion/calcination. As a result, micropatterned porous Al2O3 microdots
    with heights in µm range and large specific surface areas up to 274 m2 g−1 are
    obtained. Hence, the hydrogel fulfills a dual templating function, namely micropatterning
    and nanoporosity generation. The impact of varying the photopolymerization time
    on the properties of the products is studied. Samples are characterized by light
    and confocal laser scanning microscopy, scanning electron microscopy, energy-dispersive
    x-ray spectrometry, and Kr physisorption analysis.
