This article reports the synthesis of an eco-friendly polyurethane composite system, which was successfully prepared in a onepot synthetic pathway by combining castor seed oil (CSO), bisphenol A (BPA), isophorone diisocyanate (IPDI), and functional hybrid nanoparticles (prepared by modifying the peripheral surface of silica with 3-aminopropyltrimethoxysilane (APTMS). The urethane composites were cast as thin films on tin foils and mild steel and cured under atmospheric moisture. Attenuated total reflectance Fourier transform infrared (ATRFTIR) spectroscopy was used to characterise the cured composite films, scanning electron microscopy (SEM), energy dispersive X-ray (EDX), X-ray diffraction (XRD), thermogravimetric analysis (TGA), corrosion resistance, antimicrobial analysis, salt spray test, and water contact angle measurements. Our evaluations showed improved thermal and hydrophobic properties of the composite coatings. Also, the electrochemical and antimicrobial analyses clearly show resistance to corrosion and test organisms as the percentage composition of APTMS-SiO2 increases in the urethane system.
