Covalent grafting of organic molecular chains on amorphous carbon surfaces

Résumé

The functionalization of amorphous carbon surfaces by organic monolayers has been performed using a low-temperature (120 °C) liquid-phase process. Linear undecylenic ester CH2CH(CH2)8COOC2H5 molecules are expected to form covalent CC bonds by reaction of alkene moieties with CH terminated surfaces. Amorphous carbon (a-C:H) films were grown using plasma decomposition of CH4 and graphite sputtering in ArH2. XPS data analysis provides a quantitative estimate of the density of covalently attached molecules (0.07-0.2 × 1015 cm−2) which is compared with the functionalization of H-passivated c-Si(1 1 1) surfaces.
