Nickel nanostrands add conductivity to composites.(METALS)
Advanced Materials & Processes, January, 2005
Nickel nanostrands comprised of strands of submicrondiameter nickel particles linked in chains that range from microns to millimeters in length have reportedly been developed at the Materials and Manufacturing Directorate of the Air Force Research Laboratory, Wright-Patterson Air Force Base, Dayton, Ohio, working with Metal Matrix Composites of Heber, Utah.
So far, researchers have produced diameters ranging from 50 nm up to 2 microns, with aspect ratios in the range of 50:1 to 500:1. Nickel nanostrands are said to be very similar to carbon nanofibers and multiwall carbon nanotubes, with the added conductive properties of nickel. Researchers at Metal Matrix Composites have developed nickel nanostrand-reinforced adhesives with conductivities of 40 Siemens/cm and...
