| Résumé : |
The fabrication and applications of high aspect, sub-micron and nanoscale metal filaments, know commercially as Nanostrands is described. While there are many contemplated uses for nanostrands, most investigations of the material to date have focused on electrical conductivity in polymers and composites. The superior conductivity of metal and the high aspect ratio permits a wide variety of technology insertion techniques. The nanostrands may be added to a matrix, or the matrix may be infiltrated into a nanostrand perform. Many different applications, including polymer resins, adhesives, elastomers, paints, polymer concrete and many different composite designs have been rendered highly conductive by the addition of small fractions of the material. Nanostrands have been found to be particularly effective in controlling electromagnetic effects, such as electrostatic discharge, lightning strike and electromagnetic shielding. Nanostrand oxides are described, as are nanostrand aluminides, which retain their unique characteristics to over 500°C. Finally, the extension of the technology to create nickel coated carbon nanofibers is described and the future of these materials in the world of nanotechnology is contemplated. |
