Abstract    Recently, graphene-based systems were considered as smart nanocarriers for anti-corrosion agents. The graphene oxide (GO) nanosheets are capable of inhibitive molecule adsorption due to their numerous functional groups. In addition, the organic molecules extracted from herbs can reduce the corrosion rate, and utilization of metal cations along with organic molecules can provide a remarkable synergistic impact on the corrosion rate reduction. In this regard, this work focused on a green approach for synthesizing a control-release-based system with the application of GO, Heralecum persicum leaves extract (HPLE), and Zn cations. First, the HPLE modified GO (RGO-HPLE) nano-layers was synthesized and then modified by the Zn cations to obtain RGO-HPLE-Zn. This study was performed on the release rate of metal-organic hybrids from graphene oxide nano-plates in saline environments, and the extension of the present study would be the incorporation of synthesized nano-pigments in the epoxy polyamide resin for donating the self-healing feature. The electrochemical investigation demonstrated acceptable corrosion protection (90 %) that comes from released metal-organic hybrids. Moreover, the morphological assessment revealed the generation of a compact passive metal-organic film on the steel surface, which resulted in less electrolyte accessibility to the steel substrate.
