Nano and Macro Porous Membranes for Innovative Applications

Nano porous alumina consists of parallel pores with a narrow distribution of diameters between 20 and 400 nm with very high aspect rations. Monodomain porous alumina can be synthesized using lithography. This method allows the production of various configurations of pore arrangements that are not accessible by other state-of-the-art methods. High ordered macro porous silicon offers a mechanical and chemical stability. The pore diameters can differ from 800 nm up to 10 µm using lithographic tools. Hence macro porous silicon with its high ordered structure shows an ideal photonic crystal exhibiting novel properties for the propagation of infrared light. Because of those unique properties, nano porous alumina and macro porous silicon can be used as filters, as platforms for muliti-functional sensors, fuels cells, or templates for the fabrication of nanotubes or nanowires by electrochemical deposition or by using polymer melts.
