Rose-like superhydrophobic surface based on conducting dmit salt

The rose-like crystalline microstructures of the dmit (dmit = C3S52- = 2-thioxo-1,3-dithiole-4,5-dithiolato) salt were assembled using the combination of template method and electrochemical deposition. XRD pattern and scanning electron microscopy (SEM) show that the growth of rose-like crystals follows parabolic law and it is resulting from the anisotropic growth of the crystals which was under the influence of diffusion-limited aggregation. These special rose-like structures can be used to fabricate a superhydrophobic surface after coating a gold film and assembling a monolayer of n-dodecanethiol on these microstructures.
