Abstract
Polydopamine layers were polymerized directly from Tris-
(hydroxymethyl)aminomethane-buffered solution in a one-step immersion
process onto magnesium surface. Scanning electron microscopy showed
successful formation of a ∼1 μm thick layer. ASTM D3359−09 “Tape test”
revealed excellent adhesion of the layer. X-ray induced photoelectron
spectroscopy and Fourier transform infrared spectroscopy verified the
presence of polydopamine on the surface. Corrosion measurements were
performed in 0.1 M NaCl solution investigating the influence of coating
parameters: dopamine concentration, immersion time, solution pH, and
immersion angle. Tafel analysis revealed strong improvement of corrosion
behavior compared to bare magnesium. Polydopamine layers prepared with
optimized coating procedure showed promising corrosion properties in
Dulbecco’s modified Eagle medium. In summary, polydopamine coatings offer
a simple treatment for magnesium to improve the corrosion behavior and
could further act as intermediate layer for further surface functionalization.
