N2 - Gold pyramidal nanostructures were prepared by a one-step, nontemplated electrochemical method and were compared with electrochemically prepared rodlike and spherical gold nanostructures. The nanopyramidal surfaces show both super-hydrophobic and super-lipophobic properties due the very large fraction of air and the very small fraction of pyramidal gold particles on the sputtered gold film. It was observed that among the three kinds of nanostructured gold surfaces, pyramidal, rodlike, and spherical, the nanopyramidal surfaces show the most amphiphilic and the most amphiphobic properties before and after the modification, because it has the greatest roughness. This study provided a methodology for fabricating diverse nanostructured metal films and subsequently creating super-amphiphobic surfaces for resistance to corrosion, self cleaning, and other practical applications.
