| Abstract: | The tribologic properties of carbon nanodiscs and nanocones and their fluorinated derivatives are investigated and correlated
to their structure and chemical composition (atomic fluorine/carbon ratio). Two families of products are studied obtained
by fluorination of ill ordered and highly graphitized carbon nanodiscs and nanocones. The studies clearly point out that friction
properties of the nanoparticles are strongly dependent on the structure of the initial carbonaceous compounds. Better tribologic
behaviour is obtained when the initial nanoparticles structure is highly ordered (graphitized particles). In that case, an
optimum of fluorination rate is put in evidence. |
