 By taking advantage of the mobility and permeability of polyelectrolyte multilayer and combining layer-by-layer assembling technique with electrochemical deposition, we have developed a method to fabricate gold micro-/nano- aggregates on polyelectrolyte multilayer modified electrode. The gold micro-/nano- thin films prepared by this method have exhibited dendritic fractal structure. After being modified by dodecanethiol, this surface covered with dendritic fractal 3D gold structure exhibits superhydrophobic property. One of the advantages of this method for superhydrophobic coating is independent on the size and the shape of the substrate. Taking advantage of this point, we have fabricated the superhydrophobic coating on a gold thread surface and successfully mimicked the drag-reducing property when it floats on the gas-liquid interface. Furthermore, by preparing self-assembled monolayer of stimuli- responsive thiols on gold surface, we have successfully realized the tunable control on the surface wetting properties.
