Sažetak
Traditional methods of protecting metals from corrosion generally do not meet today's environmental requirements. As almost the entire world turns to environmentally conscious practices, new ways to protect metals that are more environmentally friendly must be found. Still, achieving both good protective properties and meeting environmental standards is a challenge. By coating metals with self-assembled molecular layers (SAMs) of fatty acids, which are generally biocompatible and degrade to nontoxic products, and combining this with the application of ionizing radiation, crosslinking of SAMs occurs on the metal surface, resulting in polymer nanocoatings with improved properties compared to SAMs. The use of ionizing radiation leads to a fast and easy-to-perform process that avoids the use of toxic agents often required for classical crosslinking. The properties of the crosslinked coatings are strongly influenced by the fatty acid used for crosslinking. In this work, the influence of the chain length of the fatty acid used on the properties of the crosslinked nanocoatings is investigated. Saturated fatty acids with chain lengths ranging from 4 to 24 carbon atoms were used to form SAMs on the surface of copper and crosslinked to form protective nanocoatings. The aim of this work was to investigate how the protective properties of the obtained nanocoatings depend on the hydrocarbon chain length of the fatty acids used for crosslinking on the copper surface. Electrochemical methods (electrochemical impedance spectroscopy and Tafel extrapolation method) were used to study the behavior of the obtained nanocoatings under simulated atmospheric conditions, while contact angle goniometry, ellipsometry and thermogravimetric analysis were used to determine the surface properties of the coatings.
