New electrochemical deposition methods for the preparation of organic-inorganic nanocomposite coatings were proposed. These methods are starts from the electrophoretic deposition (EPD) of ceramic nanoparticles and polymers. EPD is the motion that charged particles move towards the electrode in the applied electric field. Short processing time and process simplicity are the advantages of electrochemical deposition methods. Moreover, EPD methods for the fabrication of organic-inorganic of nanocomposites like ZnO films achieved non-agglomeration which is a promising method for the future industrial application. Electrode deposition was achieved by using 16-phosphonohexadecanoic acid (16PHA), octadecylphosphonic acid (ODPA), stearic acid (SA) and polyethylenimine (PEI) is used for dispersion. The characterization can be performed by XRD, SEM, Cyclic voltammetry, impedance spectroscopy, potentiodynamic studies, FTIR, TGA, DTA etc. For those organic-inorganic nanocomposites coatings, these various coatings are widely used in a great many aspects such as biomaterials, solar energy, aerospace, fuel cells, supercapacitors, and quantum dots. These materials, combine the properties of organic and inorganic components and exhibit advanced properties, which broaden application areas and improve the applications’ properties dramatically. The article is trying to illustrate the new electrochemical deposition methods for the fabrication of organic-inorganic nanocomposites and its principle.
