Transparent superhydrophobic surfaces were prepared by self‐assembly of hydrophobic n‐octa‐ decyltrimethoxysilane (H 3 C(CH 2 ) 17 Si(OCH 3 ) 3 , ODS) and (3,3,3‐trifluoropropyl)trimethoxysilane (F 3 C(CH 2 ) 2 Si(OCH 3 ) 3 , FAS3) monolayers from gas phase on transparent nanoporous alumina surfaces. Water contact angles on the silylated transparent porous alumina surfaces showed a strong dependence on the dimensions of the underlying porous structure. The highest contact angle (153°) was measured on an ODS monolayer on a porous alumina surface that had a pore diameter of about 50 nm. The superhydrophobic surfaces prepared in this work are transparent and stable which widens the range of their potential applications. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
