According to Figure 4c, the N spectrum can be fitted with the two peak components of the NH and NH + species at the binding energies of about 399.6 and 401.3 eV, respectively 51 . The bond of O═C is ascribed to the combination of GO and NH 2 ‐Ce‐MOF, confirming that the NH 2 ‐Ce‐MOF is successfully grafted on the surface of GO.…”

Herein, a new strategy for improving epoxy coatings' anti-corrosion performance has been developed, which combined NH 2 -Ce-MOF with graphene oxide (GO) by hydrothermal method. First, the nanocomposite material's morphology and structure (GO-Ce-MOF) were confirmed by Fourier transform infrared, X-ray diffraction, TG, X-ray photoelectron spectroscopy, and scanning electron microscope (SEM) studies. The dispersity of the composite in the epoxy coating was evaluated by SEM and mapping analysis. Meanwhile, the anti-corrosion of as-prepared composite coatings was investigated in detail by the electrochemical impedance spectroscopy (EIS) and the Tafel polarization curve test. The results illustrated that 2.0 wt% GO-Ce-MOF/EP greatly enhanced the composite coating's anti-corrosion performance compared to other coatings. The reasons for the improvement of the anti-corrosion performance of the composite coating are attributed to the following two aspects: On the one hand, the addition of GO can provide a physical barrier to form a labyrinth effect to slow down the invasion of corrosive media into the metal substrate, on the other hand, the modification of GO can GO-Ce-MOF achieve better compatibility and dispersion in epoxy resin.

Formulation of sustainable resource‐based organic–inorganic hybrid protective coatings have been achieved using Linseed oil‐based silica hybrid with terpolymer (TP) as basic skeletal matrix. The fabrication of TP system was performed by using systematic one pot multi‐facile steps (diol fatty amide–linseed oil‐based polyester amide TP) synthesis route. The conversion of ester amide functional ends of TP to urethane was initiated to enhance adhesiveness, impermeability, and corrosion resistivity of the processed hybrid material. FT‐IR and NMR (1H, 13C, and 29Si) studies help in verifying the chemical structure and progress of the reaction. The formulation of smooth corrosion resistive coating was further analyzed by transmission electron microscopy, scanning electron microscope, and electrochemical corrosion studies. The in‐situ tethering and homogeneous dispersion of inorganic moiety in nanoregime throughout the TP system further enhances the stability, wettability, and corrosion protection ability of the nanohybrid vegetable oil‐based coating under corrosive environment. High phase angle value at higher frequency end indicates the stability of the coating system. Such coating systems composed of sustainable resource with improved mechanical, thermal, and corrosion protective properties have great potential in future applications.

“…Metal-organic frameworks are a type of encapsulating method where metal ions are connected by organic linkers; they operate by releasing the inhibitor to form an adsorption layer on the exposed surface, and then the metal-organic framework itself impedes any penetration by electrolytes or further corrosion around the afflicted area. A key desired ability of any capsule is the controlled release of inhibitors, to not prematurely expend the limited agent within, thereby giving the coating more longevity in application [47]. Proper storage of corrosion inhibitors reduces leaks, prevents the inhibitors from interacting with the matrix, and can improve the amount of inhibitors stored within.…”

Shape memory alloys, materials capable of being deformed and maintaining the deformation and additionally capable of returning to the initial position, are valued for a range of applications from actuators to flexible microdevices. Maintaining the properties that make them useful, their ability to deform and reform, requires that shape memory alloys must be protected against corrosion, in which the integration of shape memory polymers can act as a means of protection. Thus, this review is to highlight the utility of self-healing shape memory polymers as a means of corrosion inhibition. Therefore, this review discusses the benefits of utilizing self-healing shape memory polymers for the protection of shape memory, several types of self-healing polymers that could be used, means of improving or tailoring the polymers towards specific usages, and future prospects in designing a shape memory polymer for use in corrosion inhibition.
