Abstract

This work presents an electrochemical approach for producing iron-containing metal-polymer nanocomposites and surface coatings on electrodes made of pure iron, steel, and magnesium. The synthesis occurs during the simultaneous electrochemical copolymerization of 1-vinyl-1,2,4-triazole with N-vinylpyridone and the concurrent cathodic deposition of metallic species. Characterization by Electron Paramagnetic Resonance (EPR) and Transmission Electron Microscopy (TEM) revealed that the synthesized materials contain both zero-valent iron and iron oxides, predominantly exhibiting spherical morphologies. The resulting nanocomposites contain nanoparticles with diameters between 2 and 4nm and undergo multistage thermal degradation. The obtained hybrid materials are promising for use in catalysis, biomedicine, and advanced construction materials.
