Among the methods to functionalize materials by polymer films, Graftfast© appeared to be a powerful process since it has been successfully applied to a large variety of materials: nickel, zinc, platinum, stainless steel (inox), titanium, gold, carbon fibres, aluminium but also plastics, cellulose (wood, paper), cotton and multiwalled carbon nanotubes.
Therefore, we focused on the grafting of such materials by a biocompatible polymer (PHEMA).
Conclusion The Graftfast© process, leading to the grafting of polymer on any type of materials, was presented.
