“…Surface analysis of mild steel exposed to molybdate by XPS, AES and an electron microprobe confirms the presence of FeO.OH in combination with MoO 3 [40]. In contrast, the passivation of mild steel needs oxygen in solutions containing inhibitor such as oxalate, succinate, and phthalate [41]. …”

“…Copper and carbon have no influence on the permeability of water vapor. The relative humidity inside the package is responsible for the corrosion of mild steel [16][17][18][19] and cannot be inhibited by the copper particles dispersed in the PE film.…”

The corrosion protection properties of commercially available polyethylene (PE) films containing copper and carbon were investigated and compared with pure PE films of comparable thickness. The composition of these films was analyzed by thermoanalysis and atom emission spectroscopy (ICP-AES). Electrochemical impedance spectroscopy (EIS) and packaging tests were used to determine the ability of copper-and carbon-containing PE films to protect mild steel against corrosion in humid air climates. For the here-investigated samples, no electrochemical activity of copper could be found under these conditions. In contrast to the added copper only the inserted carbon decreased the surface resistance. Additional abrasive tests imply that copper is encapsulated inside the films. For all samples, the permeability to vapor and the insertion of water were similar to the copper and carbon free reference film. The tests in the climate cabinet revealed that mild steel samples packed in copper-and carbon-containing films reached the same degree of corrosion than those in the reference films.
