Electrical conductive double-walled carbon nanotubes – Silica glass nanocomposites prepared by the sol–gel process and spark plasma sintering

Toughening and hardening in double-walled carbon nanotube/nanostructured magnesia composites

“…However, both this moderate increase and the presence of RBM peaks indicate only minor damages to the DWCNTs. No shift of the G band is observed as compared with the powder, which could indicate that no thermal residual stresses have developed after cooling down from the sintering temperature, in contrast to results reported for alumina-matrix composites [9] or DWCNTs-SiO 2 composites [36]. However, the presence of thermal stresses in the bulk of the material can not be ruled out because the polishing of the samples could contribute to relax the residual stresses at the surface.…”

The preparation of double-walled carbon nanotube/Cu composites by spark plasma sintering, and their hardness and friction properties

“…They differ from the MWCNTs used by other researchers in several aspects, namely length/diameter ratio, defect proportion, mechanical properties and tendency to gather into bundles. In addition, a given DWCNT weights much less than a MWCNT of the same length [15] and therefore much more DWCNTs will be present for a certain carbon weight loading, which can greatly modify the matrix microstructure and ultimately give better results for lower carbon loadings, as was evidenced for DWCNT-ceramic composites [16][17][18].…”

Facile Fabrication of Single-Walled Carbon Nanotube/Anatase Composite Thin Film on Quartz Glass Substrate for Translucent Conductive Photoelectrode

“…Thus, the MPM is a unique way to overcome these interactions between CNT molecules and to obtain a uniformly dispersed precursor for CNT composite thin films. In addition, single-walled carbon nanotubes (SWCNTs) tend to be easily damaged during the formation process, whereas SWCNT composites are suitable for making more conductive composites [15,16].…”
