Abstract
Corrosion problems are widespread in nature. As one of the most convenient and efficient methods for metal anticorrosion protection, anticorrosive coatings have received increasing attention. With the continuous advancement of science and technology, more novel functional anticorrosion coatings are being extensively researched. This review provides an overview of recent research progress in anticorrosion coatings and functionalized modified materials. Recent methods for performance optimization can be categorized into three main sections: modification by nanoparticles, modification by carbon-based materials, and specific functionalization (barrier effect, passivation, shielding effect, resistivity, self-repair). Through modification, the anticorrosion performance of coatings is significantly enhanced, with impedance levels improving by up to three orders of magnitude. Furthermore, modification imparts additional outstanding features to the coatings, such as high-temperature resistance, thermal conductivity, self-healing, and hydrophobicity. Finally, the future development trend of anticorrosion coatings is proposed, and several reasonable suggestions are put forward for the challenges faced.
