The main aim of this work is to enhance the surface protection of copper substrate from corrosion, by dipping process in nanocomposite PMMA-TiO2. Dipping method at constant dipping speed is applied to produce nanocomposite coat on copper substrate. The microstructure and morphology of the polymer nanocomposite coating, which includes different concentration of nanoparticles (NPs) of titanium dioxide filler (0, 1, 2 wt. %) as the reinforcing phase in PMMA matrix, was studied using SEM, AFM and FTIR. Corrosion measurement by Tafel polarization test was applied by using 3% NaCl solution. Finally, Vickers microhardness and contact angles were conducted on the nanocomposite coating surface. The results verified the formation of PMMA-TiO2 nanocomposite coating. The corrosion test illustrated that the lower corrosion rate was achieved at 2wt% TiO2 NPs. The results of the microhardness and contact angle showed that these properties depend heavily on the addition TiO2 NPs. with the best condition attained at the 2wt% TiO2 NPs.
