    Anticorrosive and antibacterial polyesteramide nanocomposite coating material was prepared from naturally available ecofriendly raw materials: Corn oil [CO] and citric acid [CA]. Corn oil was first derivatized into fatty amide diol (HECA) by base catalyzed amidation reaction. HECA was then treated with CA at desired temperature, forming CO based polyesteramide [CPEA], without any organic solvent, subsequently followed by addition of silver nitrate resulting in in situ formation of silver nanoparticles in CPEA matrix, producing Corn polyesteramide/silver nanocomposite [NCPEA]. The formation of NCPEA was supported by FTIR, UV, XRD, TEM and SEM analysis. NCPEA were applied on mild steel panels to prepare their coatings. NCPEA coatings were subjected to physico-mechanical and corrosion tests in different media. It was found that the coatings showed good scratch hardness, impact resistance, bending ability, and also performed well against various corrosive media (3.5 wt% HCl, 3.5 wt% NaCl and tap water) as investigated by Tafel analysis. Thermal analysis showed that the coatings can be safely employed upto 225 degrees C. Overall strategy is simple, using natural raw materials and employing solvent free synthesis.
