  • Patent number: 10870761
    Abstract: The present disclosure relates to novel carbon black materials characterized by a good retention of their structure in the compressed state, as shown, e.g., by a relatively high ratio of compressed OAN/OAN. The materials may inter alia be characterized by a low viscosity in dispersions and by exhibiting low electrical resistivity. Such materials can be advantageously used in various applications, for example in the manufacture of electrochemical cells such as lithium ion batteries or as conductive additive in polymer composite materials. The disclosure also describes a procedure for making such a material as well as well as downstream uses and products comprising said carbon black material.

  • Patent number: 7399804
    Abstract: Intercalates and exfoliates formed from layered materials and dendritic polymers are disclosed, together with the uses of these materials, e.g. in producing composite materials. The dispersion of layered materials in a dendritic polymer matrix (hyperbranched polymers, star shaped polymers or star branched polymers) or has not been disclosed in the prior art. The high number of end-groups per molecule of dendritic polymer combined with their unique globular architectures leads to large intergallery spacings when intercalated in layered silicates and particularly facile exfoliation in spite of the high molar mass of the dendritic polymer. The excellent processability and potential high reactivity of dendritic polymers makes them extremely promising for thermoset applications, and coatings.
