Publication number: 20090131554Abstract: There is provided an electromagnetic (EM) shielding composite and its method of manufacture having low observability and a low loading level, e.g., 1.5 weight percent, of nanotubes mixed in a base host polymer, wherein the EM shielding composite is an effective shield and absorber for broadband plane wave EM radiation. The loading levels of nanotubes are sufficiently low to leave the mechanical properties of the base polymers essentially unchanged, making this approach widely applicable to a broad range of applications.Type: ApplicationFiled: June 19, 2008Publication date: May 21, 2009Inventors: Paul Glatkowski, Patrick Mack, Jeffrey L. Conroy, Joseph W. Piche, Paul Winsor

Publication number: 20080281030Abstract: High-use temperature, lightweight polymer/inorganic nanocomposite materials are described having enhanced thermal stability and performance characteristics. These materials are made possible by new methods for synthesizing composite materials that enhance the thermal stability of the nanocomposite systems from 100-150° C. to over 450° C. These materials and techniques for their formation are enabled at least in part by the use of polar organic phthalonitrile monomers and oligomers that can exfoliate layered phyllosilicates, such as smectite clays, in percentages greater than 10% inorganic by weight. This approach offers a solvent-free direct melt intercalation technique that greatly reduces the cost of processing nanocomposites. Additionally, the use of unmodified phyllosilicates overcomes temperature limitations of prior art, which uses organically-modified layered silicates.Type: ApplicationFiled: May 22, 2006Publication date: November 13, 2008Inventors: Jeffrey L. Conroy, Joseph W. Piche, Paul J. Glatkowski, David H. Landis
