  • Publication number: 20140093728
    Abstract: A carbon nanostructure that is free of a growth substrate can include a plurality of carbon nanotubes that are branched, crosslinked, and share common walls with one another. The carbon nanostructure can be released from a growth substrate in the form of a flake material. Optionally, the carbon nanotubes of the carbon nanostructure can be coated, such as with a polymer, or a filler material can be present within the porosity of the carbon nanostructure. Methods for forming a carbon nanostructure that is free of a growth substrate can include providing a carbon nanostructure adhered to a growth substrate, and removing the carbon nanostructure from the growth substrate to form a carbon nanostructure that is free of the growth substrate. Various techniques can be used to affect removal of the carbon nanostructure from the growth substrate. Isolation of the carbon nanostructure can further employ various wet and/or dry separation techniques.

  • Patent number: 8361368
    Abstract: Certain polymer materials, including perfluorosulfonic acid ionomers, have been found to be capable of being deformed from an initial permanent shape into three or more temporary shapes. An article thus formed from such a polymer material may be used initially in a final temporary shape. As the article is progressively heated, the polymer composition reverts successively from its final temporary shape through its intermediate temporary shapes. If a suitable temperature is reached, the original permanent shape is recovered. The article may be devised to serve successive functions in each of its several shapes.
