“…Figure 6 shows the XRD patterns for pure PANI powder and PANI-coated layer on copper substrate. The observed diffraction peaks are 2h = 15°, 21°, 25°, 44°, 53°, 74°which correspond to (011), (020), ( 200), (022), ( 213), (222), respectively [29,30]. The patterns of the XRD as observed are analogous to the ICDD data number 00-053-1891 confirming the formation of polyaniline emeraldine salt in a doped form.…”

In this current paper, we report the use of inexpensive, simple electrophoretic deposition (EPD) technique in developing polyaniline (PANI) aqueous colloidal suspension coating on copper (Cu) substrate. Polyaniline nanoparticle films were deposited electrophoretically on the surface of copper sheet electrode. A colloidal suspension with high stability was produced by a liquid polyaniline in the presence of formic acid and acetonitrile as electrolyte for the EPD process. The suspension of the PANI was characterized by measuring the zeta potential of the suspension using zeta-sizer analyser. The PANI coating was used as barrier for corrosion protection of the Cu sheet. Operating parameters such as operating time, applied voltage, and the concentration were used with deposition at the cathode. Characterization such as XRD, SEM, FT-IR, and UV–Vis was carried out, and the corrosion protection offered by the PANI on the Cu surface was examined using potentiodynamic (Tafel) polarization in 3.5% NaCl solution at room temperature. As a result, the optimum parameters for obtaining a homogenous coating on the Cu sheet were attained at the voltage of 15 V and deposition time of 180 s with 50 mg/mL PANI concentration. The attained results indicated inhibition efficiency for PANI deposit of 92.92% indicating protection against corrosion.

“…However, the direction of migration can change by adding calcium cations to the solution, making this a cathodic EPD process [37,38]. In general, electrophoretically deposited GO coatings protect different metal substrates from corrosion [39][40][41]. However, the corrosion resistance depends on the morphology, adhesion, and wettability of the coating.…”

Due to the excellent properties of graphene, including flexibility that allows it to adjust to the curvature of the substrate surface, chemical inertness, and impermeability, graphene is used as an anticorrosion layer. In this review, we present the current state-of-the-art in the application of graphene in the field of protective coatings. This review provides detailed discussions about the protective properties of graphene coatings deposited by different methods, graphene-based organic coatings, the modification of graphene-based coatings, and the effects of graphene functionalization on the corrosion resistance of protective coatings.

The effect of four different cathode materials on the anodic deposition of graphene oxide (GO) nanosheets was studied experimentally. First, synthesis of graphite oxide from graphite powder was done by modified Hummers' method. Ultrasonic technique was adopted for the preparation of the stable aqueous suspension of GO by using liquid exfoliation of graphite oxide. Deposition of GO coating on copper sheets (the anode) was done via electrophoretic deposition (EPD) at the same operating condition (5V, 2 min, concentration of 0.5 mg/ml of GO per deionized water) with different cathode materials (copper, stainless steel, aluminum and graphite). The coatings’ morphological and microstructure were investigated using scanning electron microscope (SEM) and the effect of the current density in the EPD process was obtained. The change in the deposition weight was also measured. It was ascertained that the cathode’s material is a major factor can affect the GO’s EPD process and the characteristics of the final coating.
