ABSTRACT
Intrinsic tribological properties of lamellar compounds are usually attributed to the presence of van der Waals gaps in their structure. The controlled variation of the graphite's crystal and electronic structure by intercalation processes of different species (electrophile, nucleophile …) give a possibility to study in a more deeply way the friction reduction processes for low dimensional compounds. Three groups of intercalant are studied and tribological properties are correlated to structural and chemical evolutions.
