One-stop rapid decomplexation and copper capture of Cu(II)-EDTA with nanoscale zero valent iron

Towards the superlubricity of polymer–steel interfaces with ionic liquids and carbon nanotubes

“…Additionally, copper(II) ions, including ones formed at the surface termini via dangling OH bonds, enable the formation of partially soluble complexes, hence transferring copper compounds deeper and to the interfaces [46]. Therein, those compounds may be consequently reduced by the more electropositive iron phase, forming small copper nanoparticles [47]. In the case of frictional interaction between POM-C and AISI 4130, the interpretation of wear traces resembles that for the first of the analysed polymers, with the dominant role of adhesive wear polymer and its 'lumpy transfer' to the steel surface.…”
