  • Composite of exfoliated clay in soot and the preparation thereof
    Publication number: 20050250893
    Abstract: The present invention relates to a composite of an exfoliated clay pillared in a carbonized matrix. A substantially complete exfoliation of the clay can easily be achieved by first dispersing the in a viscous, high dielectric organic matrix to form a precursor composite, which can then be carbonized to form the composite of the exfoliated clay pillared in a carbonized matrix. The composite is useful as a filler, for example, to enhance the mechanical, thermal, and barrier properties of polymers.
