Sažetak
Bronze works of art and cultural heritage are exposed to pollution in open or closed atmospheres. They are susceptible to corrosion processes that lead to changes in their appearance and stability. To reduce the deterioration of cultural heritage, corrosion protection is used, which must meet the requirements of conservation ethics. Today, the most commonly used protective coating is acrylic resin, Paraloid B-72, whose drawback is the short-term protection. In this work the combination of self-assembled monolayers of selected phosphonic acids with Paraloid B-72 is examined, which would improve corrosion protection due to better adhesion between the coating and the metal surface. The protective coating is applied with a brush on metal substrates. Further, the properties of untreated and treated surfaces are compared. The protective effect of the obtained coating systems are studied by electrochemical impedance spectroscopy (EIS) in a simulated urban rain solution at pH 6.5. The structure of the self- assembled monolayers and the acrylic coating are determined by Fourier transform infrared spectroscopy (FTIR).
