摘要： 以重氮树脂(DR)/聚丙烯酸(PAA)自组装膜的微图案作为模板, 通过DNA和聚二甲基二烯丙基氯化铵(PDDA)在模板上的层层沉积制备了图案化的DNA膜. 再在其中进行Ag的化学沉积得到图案化的Ag膜. 最后利用低表面能的十二烷基硫醇对Ag膜进行表面修饰, 制备了具有超疏水性质的图案化Ag膜. 其静态接触角达到约168°.

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°.
