Sažetak
Copper is a widely used metal in the industrial applications due largely to its high thermal and electrical conductivities. A major disadvantage in the use of copper is that it corrodes, especially in aqueous environments containing oxidants. The development of coatings that provide the requisite protection is essential for its use in these applications. Self-assembled monolayers (SAMs) formed by the chemisorption of organic agents onto metallic substrates, provide a convenient method for producing organized adherent films. Self-assembled monolayers of n-alkanethiols and aromatic thiols were synthesized from an ethanolic solution on the polycrystalline copper surface. Characterization of SAMs was performed using polarization modulation infrared reflection absorption spectroscopy (PM-IRRAS), contact angle measurements (CA) and scanning electron microscopy (SEM). The protecting properties of SAMs were studied in a chloride solution (pH = 5.63) using electrochemical dc and ac techniques.
