Effect of the modified hybrid particle on the corrosion inhibition performance of polyolefin based coatings for carbon steel
Source abstract
Abstract
This work reports the corrosion inhibition performance of modified hybrid particles reinforced into polyolefin matrix. The cerium oxide coated zinc oxide hybrid particles (CeO2@ZnO) were synthesized via a chemical precipitation process. The synthesized hybrid particles were modified with benzotriazole (BTA, corrosion inhibitor). The modified hybrid particles were reinforced into a polyolefin matrix in 1 wt. % concentration. Transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), Thermogravimetric analysis (TGA), energy dispersive X-Ray spectroscopy (EDX), and X-ray photoelectron spectrometer (XPS) analysis techniques were employed to characterize synthesized and modified hybrid particles. The results demonstrated that ZnO possessed hexagonal morphology covered with spherical CeO2 particles. FTIR analysis revealed the presence of characteristic peaks of the modified hybrid particles. TGA analysis demonstrated good thermal stability of synthesized particles. UV-vis spectroscopic analysis confirmed the release of the inhibitor from hybrid particle, which was pH and time-dependent. The modified polymeric coatings' self-healing functioning was evaluated through Electrochemical impedance spectroscopic analysis. The results revealed the prominent corrosion inhibition performance of the modified coatings compared to the blank polyolefin coatings, which is attributed to the efficient release of the inhibitor from hybrid particles, making these coatings a promising solution for the protection of steel.
