“…The peak at 584 cm –1 corresponds to the symmetric stretching vibration of the Zn–O bond. In the infrared spectrum of Mn–Zn 2 SiO 4 , the appearance of an infrared absorption peak at 668 cm –1 is due to the presence of Mn . This peak is attributed to the vibrational deformation of the Zn–O bond in the arrangement of the silicate zinc structure caused by the doping of Mn.…”

Zinc silicate (Zn 2 SiO 4 ) is often used as an epoxy resin filler but is prone to damage over time, which limits its applicability. Herein, mussel-inspired polydopamine (PDA) was utilized for the capabilities of adhesion and self-healing, and Mn was doped, successfully prepared the Mn−Zn 2 SiO 4 /PDA composite, and incorporated as a filler in epoxy resin to form composite coatings. Electrochemical impedance spectroscopy testing demonstrated that after 168 h of saltwater immersion experiment, the total impedance value of the Mn−Zn 2 SiO 4 /PDA composite coating is 723.1% of that of the blank epoxy resin coating, improving the corrosion resistance of epoxy resin. Additionally, the anticorrosion mechanisms of the Mn− Zn 2 SiO 4 /PDA composite were attributed to the self-healing properties effect, shielding effect, and multivalent Mn ions magnetic induction effect. This study opens up an avenue for the development of epoxy resin composite coatings in the field of anticorrosion.

“…Due to the low crystallinity of PANI polymer nature, it shows broad and weak amorphous diffraction peaks with slight undulations between 2θ = 15°and 40°. 31,32 The XRD spectrum of the Zn 2 SiO 4 /PANI composite displays the characteristic features of both Zn 2 SiO 4 and PANI. Furthermore, by zooming in on the two sets of diffraction peaks with the highest intensity, the peaks for Zn 2 SiO 4 /PANI are higher and broader than those for Zn 2 SiO 4 alone, indicating that the incorporation of PANI increases the amorphous regions within the composite.…”

Combining two-dimensional nanostructure multioxidation state conductive polymers with traditional inorganic inhibitors to enhance the anticorrosion ability of epoxy resin coatings is an interesting research topic. In this work, the zinc silicate/polyaniline (Zn 2 SiO 4 /PANI) composite was successfully synthesized through hydrothermal and in situ polymerization methods. The two-dimensional plate-like nanostructure of the composite significantly improved the shielding effect. Moreover, the inherent semiconductivity of the composite, via the synergistic action of electrochemical protection effect and microcapacitance effect, substantially enhanced the anticorrosion properties of the epoxy resin coatings. After the immersion test in a 3.5 wt % NaCl solution, the electrochemical impedance of the Zn 2 SiO 4 /PANI composite coating was 585.8% of that of blank epoxy resin, demonstrating exceptional anticorrosion performance. This work highlights the efficacy of two-dimensional nanostructure conductive composites for preparing anticorrosion inhibitors.

Abstract2024 aluminum alloy has high strength, processing performance, and good damage tolerance performance, but it is prone to intergranular corrosion and pitting. Therefore, the development of corrosion protective coatings is essential for the aluminum alloy. In this paper, cerium ion (Ce3+) was doped into chitosan‐modified montmorillonite (Ce‐CS‐MMT) by ion exchange method, and the corrosion protective performance of Ce‐CS‐MMT epoxy coating (Ce‐CS‐MMT/EP) was investigated. The electrochemical analysis of aluminum alloy in cerium‐containing solution showed the corrosion inhibition efficiency reached 95.52%. The result indicates the corrosion inhibition effect of cerium‐containing solution was better than pure NaCl solution and MMT solution. The corrosion study of the coating illustrates that the protection rate of Ce‐CS‐MMT/EP reached 95.82%, which was higher than that 91.83% of Ce‐MMT/EP. The result indicates the resistance of charge transfer was greater and the better shielding effect for electrolyte corrosion ions than MMT and Ce‐MMT epoxy coatings, and the corrosion protective performance was excellent.
