MODERN APPROACHES TO ENHANCING THE EFFICIENCY OF EPOXY-BASED ANTICORROSION COATINGS

Purpose. To summarize and critically analyze published scientific data on the modification of epoxy polymer-based coatings in order to improve their anticorrosive properties. Research methods. The selection of literature sources was carried out using the bibliographic databases Google Scholar and Scopus. The keywords used for the search included: “epoxy resins”, “epoxy polymers”, “epoxy coatings”, “anticorrosion effect/activity”, and “corrosion inhibitors” in both Ukrainian and English. Results. A critical analysis of 22 published papers on modern approaches to improving the performance of epoxy polymer-based anticorrosion coatings was conducted. The review summarizes the most effective strategies for modifying epoxy polymer materials to develop protective coatings. It has been shown that among the nanoscale modifiers of epoxy coatings, carbon-based materials – particularly nanotubes and modified graphene – are the most extensively studied. Another promising approach to improving the anticorrosive properties of epoxy polymers is their combination with polymers of a different nature. The most intensively studied combinations involve epoxy polymers with polyanilines, polyindoles, and biopolymers. Yet another promising direction for enhancing the anticorrosive properties of epoxy resins is their modification with heterocyclic compounds, organophosphorus compounds, organosilicon compounds, and amino acids. Scientific novelty. It has been estimated that a significant number of studies focus on the incorporation of nanoscale materials into epoxy coatings, as well as on the combination of the epoxy matrix with polymers of different nature, including biopolymers. Organic compounds of various structures – particularly heterocyclic compounds, amino acids, and others – are also actively investigated as modifiers of epoxy resins. Practical value. The results of this review can be used by engineers and researchers for planning experimental and design work related to the development of anticorrosive protective coatings.
