Sažetak
Copper has been used extensively throughout history, and still is today, in a wide range of applications. Due to increasing air pollution, metals including copper can degrade faster causing large financial losses. Thus, the surface of metals needs to be protected with coatings. However, traditional coatings’ degradation products are toxic which is why they don’t satisfy today’s environmental requirements. Fatty acids spontaneously form self-assembling monolayers (SAMs) on the surface of copper due to their affinity for metals. They have the potential to replace traditional coatings because they are non- toxic compounds. The main disadvantage of SAMs is that they are relatively easily removed from the metal surface when exposed to a corrosive environment. Using gamma irradiation, SAMs can be crosslinked into polymer nano-coatings (PNC) with improved properties and durability. In this work, fatty acids with different conformations have been used for obtaining PNCs. Two mono-unsaturated fatty acids: oleic acid (OA), a cis fatty acid, and elaidic acid (EA), a trans fatty acid, C18H34O2, have been self-assembled and crosslinked using gamma irradiation on the surface of copper.
