PROCEDE DE PREPARATION D'UN MATERIAU PULVERULENT COMPORTANT DES NANOSTRUCTURES GREFFEES ET MATERIAU PULVERULENT ASSOCIE

摘要

This method comprises the following steps: - feeding at least one fuel gas through a torch (22) to generate a flame (24) at the outlet of the torch (22); - arranging a substrate (90) facing and away from the outlet of the torch (22), the flame (24) coming into contact with the substrate (90); - injecting a dispersed material into the flame (24); - growth of nanostructures in the flame (24). The dispersed material is formed from solid particles containing oxygen, at least a portion of the nanostructures formed in the flame (24) being grafted to the surface of the particles.
