Taking advantage of the stability and penetrability of layer-by-layer (LbL) films, we develop a novel method to fabricate a branchlike structure of Ag aggregates on the matrix of a LbL polyelectrolyte multilayer by an electrodeposition technique. The morphology of Ag aggregates can be adjusted by electrodeposition time and potential. Moreover, after further chemisorption of a self-assembled monolayer of n-dodecanethiol, the as-prepared surface becomes superhydrophobic with a contact angle as high as 154 degrees and a tilt angle lower than 3 degrees.
利用层层（LbL）膜的稳定性和渗透性，我们开发了一种新颖的方法，通过电沉积技术在LbL聚电解质多层膜基质上制备银聚集体的树枝状结构。银聚集体的形态可以通过电沉积时间和电位来调节。此外，在进一步化学吸附正十二烷硫醇自组装单分子层后，所制备的表面变得超疏水，接触角高达154度，倾斜角低于3度。
