Publication number: 20050250893Abstract: 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.Type: ApplicationFiled: April 8, 2005Publication date: November 10, 2005Inventors: Sudhakar Ballijepalli, Daniel Simmons, Houxiang Tang, Irina Graf, Jeff Sweeney, Tricia Wilson, Michael Nehme
