Modified halloysite nanotubes decorated with Ceria for synergistic corrosion inhibition of Polyolefin based smart composite coatings

The deteriorating effect of corrosion can be controlled by applying suitable polymeric-based coatings. In this work, polyolefin based smart composite coatings containing modified halloysite nanotubes decorated with ceria particles were investigated to analyze their anti-corrosion behavior. For purpose, (Hals) utilized as nanocarriers which loaded sodium dodecyl sulfate (SDS) a inhibitor via overnight stirring and vacuum cycling method. Hals then modified/decorated cerium oxide (CeO2) reacting nitrate (Ce (NO3)3.6H2O) hydroxide (NaOH) resulted in the formation CeO2@HAL/SDS. synthesized (CeO2@HAL/SDS) characterized energy-dispersive X-ray spectroscopy (EDX), Transmission electron microscopy (TEM), Fourier-Transform Infrared Spectrometer (FTIR), Thermogravimetric analysis (TGA), differential thermal gravimetric (DTA), diffraction (XRD) UV–vis spectroscopic analysis. TGA results demonstrated that about 32% (w/w) SDS has been into Hal, 47% CeO2 immobilized on surface Hal. UV–Vis pH-sensitive time-dependent release behavior particles. Furthermore, CeO2@HAL/SDS (1 wt%) reinforced polyolefin-based matrix, coated polished steel substrate electrochemical properties investigated. impedance (EIS) confirms promising improvement inhibition performance when compared HAL/SDS due synergistic Ce(OH)3 Fe-SDS at cathodic anodic region steel.
