Abstract: Patterned DR(diazoresin)/PAA(polyacrylic acid) SA(self-assembly) film was used as template on which a patterned DNA film was prepared by alternate deposition of DNA and PDDA(polydimethyldiallylammonium chloride). Then a patterned Ag film was obtained by means of Ag electroless deposition in the DNA patterned film. After surface modification with n-dodecanethiol the patterned Ag film, which exhibits obvious microstructure and nanostrucutre, will possess super hydrophobic properties and the contact angle of water on this surface can reach to about 168°.

Key words: Superhydrophobic, Patterning, Electroless deposition, DNA film, Ag film
