Grafting of a polymer on the surface of a carbonaceous material comprising carboxyl, amine and / or hydroxyl functions on its surface. This material is suspended in a solution comprising the polymer to be grafted, which comprises a carboxyl, amine and / or hydroxyl function, the solution also comprising a solvent for the polymer. A treatment is then carried out which causes dehydration to an amine and / or hydroxyl function to a carboxyl function, and the polymer is thus grafted onto the carbonaceous material by ester or amide bonds. Use in the cathode or anode of an electrochemical generator, in a slightly polar polymeric material, in an ink, and as a conductive deposit on a flexible plastic used as electrical contact, as electromagnetic protection or as anti-static protection. |
