Effects of laser cutting on the structural and mechanical properties of carbon nanotube assemblages

Fabrication and study of supercapacitor electrodes based on oxygen plasma functionalized carbon nanotube fibers

“…These tubes work collectively to transmit phonons and electrons through the fiber. If some of these tubular building blocks of the fibers are damaged, it will hamper the electron transfer along the fiber and will reduce the related amount of current that can be carried through [48] . Harsh plasma functionalization of the fibers can be detrimental to the ion transfer within the fiber since such surface treatment can damage the nanotubes thus hindering the ion transport.…”

Surfactant-free synthesis of copper nanoparticles and gas phase integration in CNT-composite materials

“…Porosity and morphology of the CNT ribbons as well as possible large variations on Cu-NPs surface coverage among CNTs depending on their position within the ribbon, makes it quite complicated to produce reliable and relevant figures of merit that are also practical for estimating the thickness of the Cu-NPs layer and the CNT surface coverage. 45 We have therefore tried to capture these characteristics through a semi-quantitative energy dispersive X-ray spectroscopy (EDX) analysis. EDX analysis as a function of the electron accelerating voltage can provide quantitative details on the elemental composition of a sample at various depths.…”

Laser Patterning of Aligned Carbon Nanotubes Arrays: Morphology, Surface Structure, and Interaction with Terahertz Radiation

“…Another technique is the post-growth treatment based on the ablation of an array by a focused laser beam. Applications of femtosecond [17][18][19][20][21] and nanosecond [17,[22][23][24][25][26][27] pulsed and continuous [17,[28][29][30][31] lasers were considered. Due to the high longitudinal thermal conductivity of nanotubes and significantly suppressed radial heat transfer [32,33], the patterning of arrays with shortpulse lasers does not provide a decisive benefit in the quality of cut edges [17] as it is used for the ablation of dense targets [34].…”
