TECHNOLOGY FOCUS - CERAMICS AND GLASS - Preferred Component: The substrate is glass, metal, or ceramics.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The substrate is an organic material or non-organic material.    TECHNOLOGY FOCUS - POLYMERS - Preferred Property: The first size scale is 0.1-2 mu m. The second size scale is 2-20 mu m. The third size scale is 20-200 mu m. The superhydrophobic surface exhibits apparent contact angle of at least 150degrees C. The width and depth of indentations are 5-100 mu m. The article comprises a surface exhibiting apparent contact angle of at least 160degrees . Preferred Method: Beads of a first polymer having an average size of 0.1-2 mu m are mixed in a solution of a second polymer in a solvent. The suspension is layered on the base substrate. The solvent is evaporated to obtain the layer of polymeric material comprising bead aggregates of 2-20 mu m. A web of indentations is impressed on the upper surface of the layer. The indented surface is coated with a metal film. The metal film is prepared by sputtering gold atoms in argon atmosphere. Preferred Component: The first polymer is polyvinylidene fluoride. The second polymer is polycarbonate based polymer. The solvent is chlorinated solvent. The polymeric layer is a composite material. The substrate is polymer.    TECHNOLOGY FOCUS - TEXTILES AND PAPER - Preferred Component: The substrate is textile. EXAMPLE - Tilted base substrates were coated with chlorinated solvents-based solutions comprising polycarbonate and polyvinylidene fluoride beads. A suspension was formed and dripped on the substrates and dried with a room temperature air current. The structure of the dry film showed interconnected colloidal arrays. The arrays were micro-scaled aggregates comprising polyvinylidene fluoride particles embedded in polycarbonate. The aggregates incorporate 104-106 polyvinylidene fluoride nanoparticles. Two types of substrates, quartz and polypropylene were coated. The slope of the substrate was 19-22degrees .
