As explained in the previous section, EPD can be used for the fabrication of pure octahedral cluster-based and nanocomposite thin films with no matrix or binders thanks to the charge on cluster units. In parallel, more conventional coating methods such as spin-coating, dip-coating or drop-casting are also efficiently employed despite the ceramic-like aspect of metallic clusters synthesized by solid-state chemistry. Indeed, as already mentioned molecular MC can be solubilized in many solvents which facilitates their coating process. Furthermore, the advantage of such process lies in the fact that it is possible to modify the chemistry, that is, the ligand nature or the VEC before the deposition. The main issue is to control these parameters during all the shaping process.
