“…Figure compares the FTIR spectra of the CeO 2 , PANI–CeO 2 , MBT–PANI–CeO 2 , and PAA–MBT–PANI–CeO 2 pigments. The observed peaks at 545 and 722 cm −1 were related to the stretching vibrations of CeO, which were observed in all of the spectra . Figure indicates the formation of an SDS layer on the CeO 2 nanoparticles; this was characterized by the peaks at 1724.3 and 1271 cm −1 .…”

In this study, we demonstrated a facile approach for the synthesis of nanocontainers using the encapsulation of a 2‐mercaptobenzothiazole (MBT) inhibitor; these nanocontainers were capable of responsively releasing a corrosion inhibitor and of self‐healing performances. The anticorrosive performance of the CeO2 nanocontainers was investigated with electrochemical impedance spectroscopy (EIS) measurement in a saline electrolyte via the incorporation of different weight percentages (0.5, 1, and 2 wt %) of synthesized nanocontainer in epoxy (EP) resin. The EIS results show that the loading of 1 wt % CeO2 nanocontainer containing MBT inhibitor in the epoxy (EP) coating [EP/NC MBT–CeO2 (1%)] provided the highest Rcoat, the lowest constant phase element of coating, and the optimum release of MBT at different operating pHs. The highest coating resistance Rcoat values of this coating (7.81 × 107 Ω cm2) were about 12 and 8573 times greater than those considered for EP–CeO2 and EP coatings, respectively. Different releases of the MBT inhibitor were detected at various pHs. We found that the coating operating in acidic media exhibited a better self‐healing performance. © 2018 Wiley Periodicals, Inc.

“…Furthermore, a few peaks of the CNTs in the IR curve of the nanocomposite were moved to lower wavenumbers, which is possibly caused by the interaction between the CeO 2 nanoparticles and the CNTs through the formation of hydrogen bonds between hydroxyl groups on the walls of the CNT surface and the oxygen of CeO 2 . 18 In the case of pure CeO 2 nanoparticles, the peak appearing at around 300 nm corresponds to the characteristic absorption of nano-ceria. 1b.…”

The balanced combination of nanostructured carbon materials and metal oxide nanoparticles has been considered as an efficient reinforcement material in developing next-generation multifunctional coatings. Herein, we demonstrate a general approach to fabricate a CNT based nanocomposite with the inclusion of CeO 2 nanoparticles that can be effectively implemented as a reinforcement material in surface protective coatings. The synthesized CNT/CeO 2 nanocomposite was characterized by spectral and surface morphological analyses, which indicated that the CeO 2 nanoparticles were successfully deposited onto the surface of the CNTs. The XRD pattern shows the semi-crystalline nature of the CNTs and the face centered cubic structure of the CeO 2 nanoparticles. The prepared nanocomposite has subsequently been used as a nanofiller in polyurethane (PU) coatings for surface protection of steel substrates and a remarkable synergistic effect of nano-ceria and CNTs has been observed. The corrosion resistance of steel coated with a PU coating containing CNT/CeO 2 was pointedly higher than with a pure PU coating and a PU coating with CNTs alone. This result suggests a new prospect for solving the corrosion issues encountered on steel structures in industrial applications by using multifunctional hybrid coatings with nanostructured reinforcements.
