Resumo: | Inhibition effect of poly 3-dodecyloxy aniline polymeric surfactant (PC12H) on the corrosion of aluminum in 0.5 M HCl solution was investigated using potentiodynamic polarization technique under different experimental conditions. Inhibition efficiency and thermodynamic functions for dissolution and adsorption of PC12H are compared with Poly 3-(dodecyloxy sulfonic acid) aniline (PC12SO3H) to explain the effect of terminal side chain on the corrosion protection. Data show that the presence of -SO3H as a terminal group in PC12SO3H decreases the inhibition efficiency from 88.7%, in case of PC12H, to 55.1% in case of PC12SO3H. Quantum chemical calculations were performed on PC12H and PC12SO3H to investigate the relationship between the molecular structures and their inhibition efficiencies. |

Inhibition efficiency and thermodynamic functions for dissolution and adsorption of PC12H are compared with Poly 3-(dodecyloxy sulfonic acid) aniline (PC12SO3H) to explain the effect of terminal side chain on the corrosion protection. Data show that the presence of -SO3H as a terminal group in PC12SO3H decreases the inhibition efficiency from 88.7%, in case of PC12H, to 55.1% in case of PC12SO3H. Quantum chemical calculations were performed on PC12H and PC12SO3H to investigate the relationship between the molecular structures and their inhibition efficiencies. |
