Nanostructured Cu:CuCNx composite coatings with high static and dynamic stiffness were synthesized by means of plasma-enhanced chemical vapor deposition (PECVD) combined with high power impulse magnetron sputtering (HiPIMS). Scanning electron microscope (SEM) images and energy-dispersive X-ray spectroscopy (EDS) mapping from cross-sectioned samples reveals a multi-layered nanostructure enriched in...
We present a customized technique to spin fiber from unique single-wall carbon nanotube (SWCNT) films utilizing a motorized pulling/twisting stage. The manufactured SWCNT fibers’ diameter ranged from 30 to 130μm. Electrical measurements show fusing current of 1–200mA – depending on the spun fiber’s diameter – which is close to the values known for copper wires with similar diameter. These results...
Bulk aligned multi-walled carbon nanotube films and their epoxy composites were prepared and their DC and AC conductivity studied. Nanotube films of up to 2mm thickness were grown by catalytic chemical vapor deposition. Composites of nanotubes were made by infiltrating the films with a commercial epoxy. DC electrical resistivities in the axial direction of as-grown and purified films were found to...
