“…The Lowe damage index is an indication of superior barrier protection. 62 The area with a −1 slope corresponds to the capacitive, representing the intactness, while the resistive area with the 0 slopes represents the damaged parts. This index in this study is calculated (reported in Table 4) with eq 3 given below, in which A and B are the capacitive and resistive regions, respectively.…”

Covalent organic frameworks (COFs) have been proposed as a wholly organic architecture sharing high crystallinity, porosity, and tuneability. Moreover, they exhibit highly stable structures against harsh chemical environments, including boiling water, strong acids and bases, and oxidation and reduction conditions, making them good candidates for extreme conditions. For the first time, a porous COF structure based on terephthalaldehyde and melamine was synthesized and employed as a novel nanocontainer for hosting corrosion inhibitors to provide a coating with superior active/passive anti-corrosion properties. In this study, the multiwalled carbon nanotube was utilized as a platform for growing COF (CC) to improve the coating's barrier and thermo-mechanical properties. The zinc cations were loaded into the CC structure (called CCZ) as one of the most promising inhibitors for mild steel. The COF-based nanoparticles' characterization was done by Fourier transform infrared, Raman, X-ray diffraction, thermogravimetric analysis, Brunauer−Emmett−Teller, field emission scanning electron microscopy, and transmission electron microscopy (TEM) techniques. Moreover, the Density functional theory modeling and molecular dynamics simulation quantitatively highlighted the adsorption propensity of the investigated COF structures onto the oxidized CNT-based nanostructures and the interactions of epoxy with these nanostructures. The CCZ nanoparticles (NPs) showed 75% inhibition efficiency in saline solution and 418 ppm zinc ions release after 24 h at acidic pH. The CCZ/EP coating revealed the smart release of inhibitor for 24 h and represented excellent barrier properties after 9 weeks of immersion in saline solution. In terms of mechanical properties, the elastic modulus values derived from the dynamic mechanical thermal analyzer were enhanced by 107 and 137% in CC/EP and CCZ/EP samples compared to the neat epoxy. Furthermore, the yield stress and breakpoint elongation were strengthened by 102 and 63% for the CC/EP sample, respectively. Finally, the highest pull-off adhesion strength in dry (8.53 MPa) and wet (2.7 MPa) conditions, along with the lowest adhesion loss (68.3%), was related to the CCZ/EP sample.

“…In addition to their barrier properties, 2D nanomaterials are frequently used as smart nanocarriers to load several corrosion inhibitors, e.g., Zn(II), Ce(III), phytic acid, and zinc phosphate. − Being a green, low-cost, and easy-to-obtain organic small-molecule inhibitor, dopamine (3-hydroxytyramine, DA) has application potential in the field of anticorrosion. , First, DA easily self-polymerizes into polydopamine (PDA) and forms a protective coating on the surface of nanomaterials due to the presence of numerous catechol groups. The PDA coating improves the oxidation resistance of nanomaterials and is beneficial for enhancing the compatibility between nanomaterials and polymer coatings .…”

Two-dimensional (2D) materials have a wide range of applications in the field of corrosion protection and wear resistance. The use of MXene (Ti 3 C 2 T x ) in epoxy coatings is limited due to its natural restacking tendency. Herein, MXene-ZrP@ PDA was obtained through the polydopamine (PDA) functionalization of a heterojunction composed of MXene and exfoliated αzirconium phosphate (α-ZrP). MXene-ZrP@PDA (MZP) was incorporated into a waterborne epoxy (WEP) coating to prepare an MZP/WEP composite coating. The results show that the corrosion rate of MZP/WEP (1.70 × 10 −4 mpy) is one order of magnitude lower than that of blank WEP (1.28 × 10 −3 mpy). Moreover, the average coefficient of friction (COF) of the MZP/WEP composite coating decreased by 82.06% compared with that of the blank WEP coating. The results reveal that the addition of MXene-ZrP@ PDA can significantly improve the anticorrosion/antiwear properties of WEP. Our results provide new ideas for the application of MXene/ZrP in the field of metal protection.
