Abstract :
In this study, DFT and molecular dynamic (MD) modeling were used to conduct a theoretical investigation of the potential inhibition of corrosion on Al by vidarabine. The local, global, and Fukui functions were used to calculate the molecule s reactivity. It is hypothesized that vidarabine will display physisorption with Al surface based on the predicted adsorption energy of the system and the binding energies obtained (58.923, -58.923 Kcal/mol). The negative value of the EHOMO, which is -5.050 eV, predicts the mechanism of vidarabine on the surface of Al to be physisorption. The molecular dynamics and the quantum properties suggest that the molecule vidarabine can operate as a potent corrosion inhibitor.
