Grafting a polymer at the surface of a carbonated material containing carboxyl amine and/or hydroxyl functions at its surface. This material is suspended in a solution comprising the polymer to be grafted, which includes a carboxyl amine and/or hydroxyl function, the solution also comprising a solvent of the polymer. This is followed by a treatment causing dehydration into a carboxyl function, an amide and/or hydroxyl function and the polymer is thus grafted on the carbonated material by means of ester or amide bonds. Utilization in the cathode or anode of an electrochemical generator, in a polymer material with low polarity, in an ink, and as a conductive deposit on flexible plastic used as electrical contact, electromagnetic protection and antistatic protection. |
