It can use for the especially carbon fiber which designates the production of the composite material as purpose, it reforms in reforming manner and this way of the surface of the carbon material by the electrochemistry reduction of the diazonium salt the carbon material

摘要

Process for modyfying the surface of carbon-containing materials by electrochemical reduction of diazonium salts, applicable in particular to carbon fibres for composite materials, and carbon-containing materials so modified. According to the process, the carbon-containing material is used as a cathode (3) in an electrolysis unit containing a diazonium salt solution ArN2x- (2) in an aprotic solvent and by electrochemical reduction to a suitable potential, the aromatic group (Ar) is bound to the carbon-containing material. Any aromatic group can be bound in this way to the carbon-containing material, for instance C¿6?H4NO2, C6H4NH2, C6H4COOH, and then reacted with suitable compounds.
