چکیده    Organic coatings, such as epoxy polyamide (ep), have been suggested as a promising way for controlling the metal's corrosion in different environments. however, owing to the existence of ample defects in ep structures, the ep cannot resist fo the long term. to overcome this issue, the authors designed a network to provide a stronger barrier platform for long intervals and donate active protection/self-healing properties for the time that a mechanical defect occurs. the electrochemical results revealed a significant improvement for the scratched coating, which was about 120 kohm.cm2 for 48 h. moreover, the fe-sem and eds/mapping analysis clarified the generation of metal-organic film, which was constructed by the released inhibitive agents from go nanosheets. on the other hand, the outcomes of the electrochemical assessments stated a remarkable resistance of the intact ep coatings by incorporation of go@gse-zn in ep polymeric matrix due to hydrophobicity enhancement of the nanocomposites as well as providing a longer pathway for the electrolyte diffusion into the coating. moreover, the pull-off adhesion test was accomplished to survey the impact of additives on the adhesion/cohesion coatings, and the results demonstrate an acceptable improvement. all in all, the authors recommended a new green approach for enhancing the ep coatings application in industrial procedures that can help the world environmental concerns and leads to financial management.

Abstract    Organic coatings, such as epoxy polyamide (EP), have been suggested as a promising way for controlling the metal's corrosion in different environments. However, owing to the existence of ample defects in EP structures, the EP cannot resist fo the long term. To overcome this issue, the authors designed a network to provide a stronger barrier platform for long intervals and donate active protection/self-healing properties for the time that a mechanical defect occurs. The electrochemical results revealed a significant improvement for the scratched coating, which was about 120 kohm.cm2 for 48 h. Moreover, the FE-SEM and EDS/mapping analysis clarified the generation of metal-organic film, which was constructed by the released inhibitive agents from GO nanosheets. On the other hand, the outcomes of the electrochemical assessments stated a remarkable resistance of the intact EP coatings by incorporation of GO@GSE-Zn in EP polymeric matrix due to hydrophobicity enhancement of the nanocomposites as well as providing a longer pathway for the electrolyte diffusion into the coating. Moreover, the pull-off adhesion test was accomplished to survey the impact of additives on the adhesion/cohesion coatings, and the results demonstrate an acceptable improvement. All in all, the authors recommended a new green approach for enhancing the EP coatings application in industrial procedures that can help the world environmental concerns and leads to financial management.
