As part of promoting eco-friendly research & development, corrosion chemistry encourages green inhibitors for metal corrosion prevention. Thespesia Linoleic acid, n-Hexadecanoic acid, trans-Squalene, Phytol were identified as the active components responsible for corrosion inhibition. The optimum concentration of 500 ppm could deliver protection with efficiency in the range of 97%-98%. Additionally, we extended the study to evaluate the extract's capability for its use in the paint industry. The remarkable potential of the TiO2-TP composite coating thus developed was illustrated by physico-chemical, electrochemical, and surface analyses. According to the electrochemical impedance spectroscopy (EIS) study, the applied leaf extract loaded coatings resist corrosion of CS at efficiencies of 97.9%, 91.6%, and 98.5% in 1M HCl, 1M HCl at 80℃, and rainwater mediums, respectively. The proposed composite coating is undoubtedly promising for industrial application and is also recommended by green protocols.
