Synthesis of a multi-functional zinc-centered nitrogen-rich graphene-like thin film from natural sources on the steel surface for achieving superior anti-corrosion properties

Abstract

Novel zinc-centered graphene-like compounds were developed on the metal surface using nature-based phytochemicals based on Papaver somniferum extract and zinc salt. Through the FTIR, UV–vis, GIXRD, and Raman analyses, the deposited film composition on the substrate was investigated. Outcomes from the EIS indicated an inhibition degree of 99 % on the protected samples after 11 days of exposure, expressing the high corrosion retardation durability of the deposited film. Polarization test evidenced mixed inhibition with anodic inhibition dominancy. The formation of a dense graphene-like based film composed of Zn-poppy complexes over the metal surface was affirmed by AFM, SEM/EDS, and contact-angle techniques.
