A method for manufacturing metal-CNT composites is disclosed. The method comprises providing an agglomerate of CNTs, filling interstices of the CNT agglomerate in a plating solution, so as to form a metal phase, in which the CNTs are embedded. The CNT agglomerate is compressed with a clamping appliance when the metal phase is formed. A further aspect of the invention relates to metal-CNT composites with high CNT content.

Highly compact metal-CNT composites and manufacture thereof

According to a first aspect of the invention, a method for producing a metal-CNT composite material is proposed. The method includes providing a layer of CNT by depositing CNT coated with a polyphenol or poly(catecholamine) coating and filling the interstices of the carbon nanotubes layer with a metal so as to form a metal matrix, in which CNT are embedded. The filling is effected by electrode position or by electroless deposition. The polyphenol or poly(catecholamine) coating is crosslinked by metal ions, the metal ions promoting, as metal seeds, adhesion and/or growth of the metal matrix during the filling step. A further aspect of the invention relates to the metal-CNT composite obtainable by the method.
