| Abstract | ||||
| Zinc (Zn) and magnesium (Mg) network structures have been prepared chemically in presence of stable aqueous dispersion of nanocarbon (NC) to form the corresponding hybrid sol gel (HSG) of Zn /Mg /NC. Morphological studies and particle size distribution of the formed (HSG) have been determined via SEM/EDX, TEM and dynamic light scattering (DLS) respectively. The prepared (HSG) of different weight percent (3, 6, 9, 12 %) has been incorporated into ecofriendly anticorrosive water born paint formulations to protect carbon steel from corrosion. The painted metal panels have been tested for degree of rusting and blistering resistance in accordance with ASTMD. The physico- mechanical properties of the coated panels have been also investigated. The effect of the prepared HSG in enhancing corrosion protection efficiency IE% of the painted panels has been monitored by potentiodynamic polarization and electrochemical impedance spectroscopy. The results revealed that as the concentration of the prepared HSG increases as the IE% increases. Maximum inhibition efficiency IE% up to 96.5% was obtained. As far as we know, these featured corrosion resistances for the prepared paint formulations have not been reported yet in the open literature. | ||||
