propyl methacrylate (TMSPMA) is used to coat the surface of halloysite nanoparticles, resulting in a less hydrophilic clay surface and improved nanoparticle dispersibility in the epoxy polymer (EP). The efficiency of epoxy/clay nanocomposites in terms of thermal, mechanical, and barrier properties was studied. The results of XRD, SEM/EDX, TEM, and TGA all show that halloysite nanoparticles are silanized. EP-TMSPMA/clay coatings have a high degree of hydrophobicity (WCA: 139°) and surface roughness. Electrochemical techniques were used to investigate the corrosion resistance of coated steel substrates. The coating resistance of the EP-TMSPMA/clay nanocomposite coating was found to be over 62.98% higher than the EP coating. Even after 15 days of immersion, electrochemical tests demonstrate that EP-TMSPMA/clay has a higher coating resistance (R coat ) than plain epoxy coated mild steel. At 15 days of immersion, SECM data show that the dissipation of Fe in the EP-TMSPMA/clay coated substrate is significantly lower than the pure epoxy coated substrate. Furthermore, mechanical testing (hardness, adhesion, and tensile strength) revealed that the epoxy/silane/clay nanocomposites had improved mechanical properties. Silanized clay including epoxy nanocomposites has excellent barrier, hydrophobic, and mechanical qualities, as well as excellent oxygen and water repellent capabilities. EP-TMSPMA/clay has the best characteristics of all of the coated nanocomposites examined. Because clay/silanes are environmentally safe, this form of coating could be used as a viable coating material for industrial purposes.

Polyepoxides are a kind of chemical polymerization that is widely employed in several industrial purposes. Due to their macromolecular structure, polyepoxides offer superior superficial treatment and antierosion activity compared to basic organic corrosion inhibitors. During metal-inhibitor interactions, the polyepoxides outlying glacial efficient clusters operate as adsorption centers. Numerous polyepoxides have been employed as anticorrosive coating materials in both pure and cured forms, most notably for ferrite in acidic and NaOH solutions. The majority of polyepoxides operate as inhibitors of interface and mixed-type corrosion. Numerous computer models have been done to illustrate the anticorrosive properties of polyepoxides on metallic shells and their adsorption behavior. However, because the majority of polyepoxides have low solubility, they are best used as anticorrosive coating materials. Numerous polyepoxides-based coatings have been created and effectively applied on ferrite and aluminum in salt-water solution according to a review of the literature. Natural and synthetic additives can be used to further enhance the anticorrosive properties of polyepoxides coatings. This review article compiles published findings on the anticorrosive properties of pure and cured polyepoxides for a variety of metals and alloys in a variety of electrolytes.

The anticorrosion, flame retardant, and mechanical properties of polyurethane (PU) coatings have been improved by the integration of nickel disulfide (NiS2), 2,5‐Bis(4‐aminophenyl)‐1,3,4‐oxadiazole (BAO), and graphene oxide (GO). The structural, morphological, dielectric, and hydrophobic behaviors of the films were characterized for the different formulations of coatings such as pure PU, PU‐NiS2, PU‐BAO/NiS2, PU‐GO/NiS2, and PU‐GO/BAO‐NiS2 (nanocomposite) by means of scanning electron microscope/X‐ray energy dispersive spectroscopy, transmission electron microscope, thermogravimetric analysis, X‐ray photoelectron spectroscopy, X‐ray diffraction, and contact angle measurement. As a result, with the addition of only 0.3% GO/BAO‐NiS2, the dielectric constant of PU was increased by 81‐fold at 1 Hz. Additionally, the nanocomposite had significantly lower peak heat release rate and overall heat released values than pure PU, a difference of 57% and 51%, respectively, demonstrating its greater flame retardancy. The electrochemical techniques and mechanical testing confirmed that GO/BAO‐NiS2 (0.3%) composite exhibit enhanced anticorrosive, hydrophobic, flame retardancy, and mechanical performance of the PU coating. The super hydrophobic behavior is confirmed by its water contact angle of 165°. Furthermore, the resistance of the nanocomposite was found to be much higher (16,985.6 kΩ.cm2) than that of the pure PU (145.4 kΩ.cm2) and the microhardness and tensile strength were increased sharply. Therefore, the nanocomposite could act as a potential coating material for industrial applications.
