  • Patent number: 9527740
    Abstract: The present disclosure relates to ground expanded graphite agglomerate compositions, methods for making such agglomerates, their use as conductive additives, and conductive composites including such ground expanded graphite agglomerates. The disclosure also relates to methods for making such composites and the use of such composites in preparing thermally conductive materials. The agglomerates may be characterized by a certain softness allowing the agglomerates to dissolve, for example, through shear forces applied during compounding, thereby leading to an improved feedability and a highly homogenous distribution of the expanded graphite material in the composite matrix.
    Type: Grant

  • Publication number: 20080279749
    Abstract: The present invention relates to a process for further processing of the carbon-containing residue derived from fullerene production and from carbon-nanostructures production, characterized in that the residue is functionalized via introduction of chemical substituents, and the functionalization is carried out during or after the production process. The functionalized carbon-containing residue obtainable by the process is also provided, as is its use as a hydroxylating agent, wetting agent, additive in rubber compounds, and for tether-directed remote functionalization.
