  • Catalyst system for a multi-walled carbon nanotube production process
    Patent number: 7923615
    Abstract: The present invention relates to a catalyst system for the selective conversion of hydrocarbons into multi-walled carbon nanotubes and hydrogen comprising a compound of the formula: (Ni,Co)FeyOz(Al2O3)w wherein ‘y’ represents the molar fraction of Fe relative to Co and Ni and wherein 0.11?y?9.0, 1.12?z?14.5, and 1.5?w?64.
    Type: Grant
    Filed: August 25, 2006
    Date of Patent: April 12, 2011
    Assignee: Nanocyl S.A.
    Inventors: Ricardo Prada Silvy, Christophe Pirlot, Benedicte Culot
  • Conductive polyolefins with good mechanical properties
    Patent number: 7863366
    Abstract: Processes for preparing reinforced polymeric material and the materials formed therefrom are discussed herein. The processes generally include providing a polymeric matrix, providing single-wall carbon nanotubes (SWNT) or multiple-wall carbon nanotubes (MWNT), purifying by the nanotubes in a single step of dissolving a support and catalyst particles with an agent appropriate to the nature of the support to form a purified support, functionalising the purified support by reaction with an alkylamine to form a functionalized support, dispersing the nanotubes in the polymeric matrix by mixing in the molten state to form a mixture and optionally orienting the mixture by stretching.
