Abstract

Polydopamine (PDA) is a promising synthetic surface modifier that can be deposited on a wide range of substrates providing a chemically reactive surface with catechol and amine groups for functional coatings. In this study, bivalent metal ions were used to dope PDA for applications in functional conductive coatings. X-ray photoelectron spectroscopy (XPS) was used to verify doping in the PDA. To confirm doping in the matrix, the binding energy of characteristic peaks, shift in peaks and new signals indicating interactions between the dopant and PDA matrix were analyzed. Focused ion beam (FIB) cross-sectioning was used to measure the thickness and presence of the FeCo film layer demonstrating the doped PDA can be used for electrodeposition.
