Publication number: 20150056447Abstract: The present invention relates to a method for enhancing the adhesion of CNTs to the surface of a material, including the following steps carried out under an inert gas current or currents optionally mixed with hydrogen: (i) heating the material including CNTs on the surface thereof in a reaction chamber, to a temperature of between 500° and 1,100° C.; (ii) introducing into said chamber a carbon source consisting of acetylene and/or xylene, in the absence of a catalyst; (iii) exposing the heated material to the carbon source for a period of time sufficient to ensure the production of a carbon layer of controlled thickness on the surface of said material and said CNTs covering same, as shown in the figure below; and (iv) optionally recovering the material thus covered after cooling, upon completion of step (iii). The invention likewise relates to hybrid carbon-coated reinforcements and to the uses thereof for preparing structural and functional composite materials or for preparing paints or varnishes and wires.Type: ApplicationFiled: January 11, 2013Publication date: February 26, 2015Inventors: Jinbo Bai, Youqin Lin, Anthony Dichiara
