I am trying to electrochemically deposit previously synthesized polyaniline blended with manganese doped zinc sulphide. Is there any way to do so or do I have to synthesis polyaniline electrochemically?
The following information may be useful for your research
Strongly adherent polyaniline coatings were electrochemically synthesized on mild steel from an aqueous salicylate medium. Thesecoatings were characterized by cyclic voltammetry, UV-visible absorption spectroscopy, Fourier transform infrared spectroscopy (FTIR)and scanning electron microscopy. The extent of the corrosion protection offered by polyaniline coatings to mild steel was investigated in
aqueous 3% NaCl solution, 0.01 M Na2SO4 solution and in aqueous solutions of NaCl+Na2SO4 with different concentrations bypotentiodynamic polarization technique and electrochemical impedance spectroscopy (EIS). The results of these studies reveal that thecorrosion resistance of the polyaniline-coated mild steel is significantly higher and the corrosion rate is considerably lower than that of uncoated steel.

Thank you sir, but I already have polyaniline crystals blended with ZnS. I am trying to coat on ITO glass electrochemically.
Is Your PAni doped or undoped ? What is the dopant ? Is the PAni/ZnS-Mn blend soluble in any common solvent ? Is the blend fusible ?
If it is possible to dissolve Your undoped polyaniline, electrochemical deposition may be performed, exploiting the low solubility of doped PAni to make it precipitate on the electrode/substrate, although this rarely yields highly organised layers.
Should Your type of PAni be insluble (or You do not wish it dissolved), the question would be whether the polymer blend is fusible - if so, melt-processing techniques may be used.
Are you intending a particular polyaniline phase e.g. emeraldine? Providing more specifications on the type of phase may make it easier to have an appropriate answer. Note that not all phases are electrically conducting.
