“…Finally, at the highest concentrations studied herein, the individual Cu crystallites have SWCNTs encapsulating them ( Figure 1h). A similar morphology was observed in the electrodeposition of Cu and surfactant dispersed MWCNTs [26,27]. Irrespectively, it is clear that the SWCNTs have altered the nucleation of copper particles during the electroplating process.…”

Single walled carbon nanotubes (SWCNTs) are used as a component of a plating solution of CuSO4 for direct current electrodeposition of Cu–SWCNT composites with varying nanotube proportions without the use of either a surfactant, a dispersing agent, or functionalization of the SWCNTs. The Cu–SWCNT composites are characterized by scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and Raman spectroscopy. The composites are comprised of metallic Cu and SWCNTs with minor oxide impurities, as well as the residual (Fe) catalyst from the unpurified SWCNTs, in addition to displaying nanotube-mediated morphological differences. EDX analysis of carbon (wt%) is close to quantitative with respect to the wt% of SWCNTs added to the electrolysis solution. The presence of SWCNTs decreases the oxidation of the copper, as well as changing the identity of the oxide from CuO, for electrolysis of Cu, to Cu2O. Hard adherent Cu–SWCNT coatings are prepared by the addition of Cu powder to the electrolysis solution. The approach described in this paper will enable controlled synthesis of metal-nanomaterial composites that can potentially be processed further into high ampacity electrical conductors.

“…For the composite worn surface shown in Figure 6b,c, the worn surfaces were much smoother due to less plastic deformation on the contact surface [34]. As the soft Cu matrix easily flaked off during the wear process, the CNTs (high content) were exposed and formed the lubricating film on the worn surface [25]. The lubricating film can significantly reduce the adhesive wear between the GCr15 ball and the Cu matrix, which resulted in low wear weight loss.…”

“…In order to increase CNT hydrophilicity and improve incorporated CNT content, CNTs were immersed in strong acid to achieve functionalization before electrodeposition. The strong acid treatment process was complex and the effect was limited [13,22,23,24,25,26]. A simple and feasible method is still required to fabricate Cu-CNTs composite coatings with high CNT content and uniformly distributed CNTs.…”

Cu-carbon nanotubes (CNTs) composite coatings with high CNT content and uniformly distributed CNTs were successfully prepared via jet electrodeposition. Pristine CNTs, without any treatment like acid functionalization, were used. Anionic surfactant sodium dodecyl sulfate (SDS) was used to increase the wettability of the CNTs and improve the content of incorporated CNTs. With an appropriate SDS concentration (300 mg/L) in the electrolyte, the incorporated CNT content is as high as 2.84 wt %, much higher than the values reported using conventional electrodeposition (0.42–1.05 wt %). The high-content CNTs were uniformly distributed in the composite coating. The surface morphology of this composite coating (2.84 wt % CNTs) was flat due to the uniform electric field in jet electrodeposition. In the wear test a with load of 1 N and sliding speed of 0.02 m/s, the wear rate of this composite coating was 1.3 × 10−2 mg/Nm, 85.4% lower than that of pure Cu. The enhanced wear performance of Cu-CNTs composite coatings can be attributed to high CNT content and flat surface morphology.

“…These properties depend to a large extent on the nature and content of the reinforcement used. Copper composite coatings based on different carbon structures were studied: carbon nanotubes [29,30], graphene oxide [28], and carbon nanofibers [31,32]. Carbon nanotubes (CNT) with a few micrometers in length and diameters on the order of nanometers [33] can be used as reinforcements in composite coatings, because they have unique mechanical, thermal and electrical properties [34].…”

This research deals with the deposition of copper on a steel substrate. Two different methods were investigated: electrochemical and magnetron sputtering. The deposition parameters were optimized to obtain a coating layer with uniform granular structure and good adhesion to the substrate. As a novelty, carbon nanowalls (CNW) were used as reinforcement in copper coatings on the steel surface. The morphology of the coatings, adhesion and Vickers microhardness were performed to emphasize the CNW influence on the coating properties. Open circuit potential and Tafel analysis were used for electrochemical characterization. These kinds of CNW-copper composite with improved hardness and adhesion and surface electrical resistance around 1 Ω·cm could have miscellaneous applications in different domains such as aerospace, electronics, automotive and power-generation.
