Abstract

Invar (Fe₆₅Ni₃₅), a 'zero' thermal expansion alloy consisting of Fe and Ni, has been successfully introduced into carbon nanotubes by pyrolysing, at 800 °C, aerosols of NiCp₂/FeCp₂ mixtures dissolved in C₆H₆; scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HRTEM) studies reveal the presence of flake-like structures (ca. 1-2 mm²) consisting of filled/aligned carbon nanotubes (≤200 μm in length and ≤80 nm in diameter) in a carpet pile-like configuration; analysis of the filling material (≤500 nm in length and ≤40 nm in diameter) by X-ray powder diffraction and high-resolution electron energy loss spectroscopy (HREELS) line scans, confirmed that Invar was formed; this appears, to the best of our knowledge, to be the first report of mixed metal alloy nanowires forming inside carbon nanotubes.
