利用逐层膜的稳定性和透过性，我们发展了一种新的方法，通过电沉积技术在多层膜的基质上制备银聚集体的树枝状结构。银团聚体的形态可以通过电沉积时间和电位来调节。此外，在自组装的正十二硫醇单分子膜进一步化学吸附后，所制备的表面变得超疏水，接触角高达154度，倾斜角小于3度。
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.
