Polysulfobetaine films prepared by electrografting technique for reduction of biofouling on electroconductive surfaces

► Poly(2-(dimethylamino)ethyl methacrylate) is covalently attached to the electroconductive substrate by electrografting polymerization. ► Electrografted film can be effectively modified to the corresponding sulfobetaine structure. ► Electrografted film was thoroughly characterized by various complementary techniques in terms of surface chemistry and topography. ► Non-biofouling properties were confirmed for electrografted film after modification to zwitterionic character.
