A simple and scalable synthetic strategy was developed for the fabrication of one-dimensional SiC nanostructures—nanorods and nanowires. Thin sheets of single-walled carbon nanotubes (SWNTs) were prepared by vacuum filtration and were washed repeatedly with sodium silicate (Na2SiO3) solution. The resulting “glassy buckypaper” was heated at 1300–1500 °C under Ar/H2 to allow a solid state reaction between C and Si precursors to form a variety of SiC nanostructures. The morphology and crystal structures of SiC nanorods and nanowires were characterized using scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HR-TEM), energy-dispersive X-ray spectroscopy (EDX), electron diffraction (ED), and X-ray diffraction (XRD) techniques. Furthermore, electrical conductance measurements were performed on SiC nanorods, demonstrating their potential applications in high-temperature sensors and control systems.

As-synthesized Fe-CNT buckypaper shows strong anisotropic behavior, which can be attributed to the different response of Fe-nanowires inside carbon nanotubes with high aspect ratio in different applied magnetic field.">

ZnO nanostructures have been electrochemically synthesized on three-dimensional, interconnected, and porous carbon nanofiber Buckypaper substrates

Aligned multi-walled carbon nanotube (MWCNT) growth has beenused in CNT film synthesis through the . In thisprocess, "forests" of MWCNTs are pushed flat in a single direction,compressing their vertical orientation into the horizontal plane,which results in the formation of high-purity buckypaper with nofurther purification or treatment required. By comparison, when abuckypaper sample was formed from the 1 ton compression of chemicalvapor deposition (CVD) generated MWCNT powder, any application of asolvent led to the immediate swelling of the film till it revertedinto particulate matter. It appears that for the CNT powder used,compression alone was insufficient to generate robust buckypaperand highlights that the aligned growth methodology generatesin-situ tube-tube interactions not found in CVD CNT powderand are preserved through to the domino pushing formation ofbuckypaper.
