PROCESS FOR MODIFYING THE SURFACE OF CARBON-CONTAINING MATERIALS BY ELECTROCHEMICAL REDUCTION OF DIAZONIUM SALTS, APPLICABLE IN PARTICULAR TO CARBON FIBRES FOR COMPOSITE MATERIALS; CARBON-CONTAINING MATERIALS SO MODIFIED

摘要

the invention relates to a method for surface modification of carbonaceous materials by electrochemical reduction of diazonium salts, which can be used in particular for carbon fibre composites for the realization of carbonaceous materials, and modified.according to this method, the carbonaceous material is used as a cathode (3) in an electrolytic cell containing a solution (2) of the diazonium salt in an aprotic solvent and arn2x by electrochemical reduction potential is set to a suitable aromatic group on the material fuel) onu00e9.we can fix on the carbonaceous material is an aromatic group, for instance c6h4no2, c6h4nh2, c6h4cooh and respond with appropriate compounds.
