The use of nanomaterials in coatings can improve the corrosion resistance and other properties of traditional coatings, thereby enabling the creation of new functional coatings. The quantum effects arising from the small size of nanoparticles and their large specific surface area endow nanocomposites with many special properties. The adhesion, impact resistance, flexibility, aging resistance, and corrosion resistance of composite coatings are improved, and additional special properties such as self-cleaning, antimicrobial effects, and wave absorption are also acquired. Currently, the inorganic nanoparticles studied for use in corrosion-resistant applications are mainly SiO2, TiO2, ZnO, and carbon nanotubes (CNTs), among others. However, there are two issues regarding the use of nanoparticles in coatings: one is the problem of uniform dispersion of the nanoparticles within the resin, and the other is the interface issue between the particles and the matrix resin.
