<P>PROBLEM TO BE SOLVED: To graft a polymer at the surface of a carbonated material containing carboxyl, amine and/or hydroxyl functions at its surface. <P>SOLUTION: The carbonated material is suspended in a solution comprising the polymer to be grafted, which includes the carboxy, amine and/or hydroxy function, and also comprising a solvent of the polymer. This is followed by a treatment causing dehydration into a carboxy function, an amide and/or hydroxy function and the polymer is thus grafted on the carbonated material by means of ester or amide bonds. The surface-modified carbonated material is used 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. <P>COPYRIGHT: (C)2008,JPO&INPIT |
