الملخصIn this study, pH-sensitive hydroxyapatite particles loaded with tannic acid were incorporated in polyolefin-based coatings for the corrosion protection of carbon steel. Transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA) were used to characterize the hydroxyapatite particles loaded with tannic acid (Tannic-HAP). Electrochemical impedance spectroscopy (EIS) was employed to study the protective performance of the reference and modified polyolefin coatings. The results suggest that modified coatings showed improved corrosion performance compared to the unmodified coatings. The combination of tannic acid and hydroxyapatite contributed to a more effective protection of coated carbon steel.
