ABSTRACT:<\/span><\/p>\n

Perfluorocarbon residues, i.e. perfluoroethyl (PFE), CF(3)CF(2)-, perfluoro-n-propyl (PFnP), CF(3)CF(2)CF(2)-, perfluoro-isopropyl (PFiP), (CF(3))(2)CF-, and perfluoropolyether (PFPE) chains, e. g. (CF(2)CF(2)O)(m)(CF(2)O)(n), were covalently bonded on the surface of carbon black (CB) and diamond-like carbon (DLC) using PFPE and perfluorodiacyl (PFDA) peroxides. The thermal decomposition of the peroxidic moieties of these perfluorinated peroxides generated reactive perfluorinated radicals. The perfluorinated free radicals could directly bond to the sp(2) sites avoiding any spacer, which usually decreases both thermal and chemical stabilities of the resulting materials. The effects of chemical treatment on the carbonaceous materials were studied using X-ray Photoelectron Spectroscopy (XPS), Scanning Electron Microscopy (SEM) and Contact Angle (CA) measurements. The surface areas of CB powders were determined by the BET technique; the morphology of the DLC coatings was evaluated by Atomic Force Microscopy (AFM) and the friction forces were measured by means of Lateral Force Microscopy (LFM).<\/p>\n
