“…The dependence of the hardness has a maximum at 0.5 wt. % FS attaining a value of 160 ± 4 HB, which is higher than the majority of the data reported earlier for any Cu-C composites [ 1 , 2 , 3 , 4 , 5 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 ]. A further increase of FS concentration leads to the hardness falling down to 75 HB that may be explained by increase of Cu-boundaries quantity and appearance of soft FS agglomerates due to its inhomogeneous distribution.…”

“…Copper-based composites reinforced with carbon nanoparticles attract interest due to a combination of mechanical and electrical properties [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ]; besides, these composites mostly have low friction coefficient and wear [ 14 , 15 , 16 , 17 , 18 , 19 ], which is necessary for sliding contact application.…”

Copper-based composite materials strengthened with nanosized fullerene soot particles were produced by mechanical milling and hot pressing technology with a content of carbon up to 5 wt. %. The microstructure of the composite powders and the compacts prepared using them were examined by light microscopy, SEM, EDS, XRD, and XPS; hardness, heat conductivity, and tribological characteristics were measured. The interesting feature of the observed microstructure was a “marble” pattern formed by a white boundary net. The study shows homogeneous distribution of carbon inside the copper grains and its lower concentration in the grain boundaries. The effect was caused by a reaction of carbon with oxygen adsorbed by the copper particles surface. The maximal hardness of the material is 160 HB for the sample with 0.5 wt. % of fullerene soot; this material has the minimal friction coefficient (0.12) and wear in a dry friction condition. Heat conductivity of the material (Cu-0.5 wt. % C) is 288 W/m*K.

“…The addition of graphene to Cu has been shown to affect copper's microstructure and conductivity. [71,[84][85][86] Most notably, a very small loading of graphene (<0.001%) is required to cause measurable improvements in copper's conductivity. High-temperature/pressure (950 ºC and 50 MPa) processing of several Cu-CVD graphene films has resulted in conductivities as high as 117% IACS at room temperature.…”

Advanced electrical conductors that outperform copper and aluminum can revolutionize our lives by enabling billions of dollars in energy savings and facilitating a transition to an electric mobility future. Nanocarbons (carbon nanotubes and graphene) present a unique opportunity for developing advanced conductors for electrical power, communications, electronics, and electric machines for the defense, energy, and automotive industries. Herein, the major research progress in the field of advanced nanocarbon-based and metalnanocarbon conductors is compiled. The benefits and drawbacks of advanced conductors are also elucidated with respect to conventional ones and their materials science, mechanical and physical properties, and characterization are discussed. Finally, several areas of future research for advanced electrical conductors are proposed.

“…GO was synthesized by a modied hummer's method 35 with a mesh size of 1000 mm of natural graphite ake powder. Initially, 25 ml (90%) of concentrated H 2 SO 4 was heated at 90 C, then 5 g of each of K 2 S 2 O 8 , P 2 O 5 and 6.2 g graphite was added keeping temperature at 80 C for 4.5 h. This solution was then treated with 200 ml of H 2 SO 4 and 30 g of KMnO 4 at a temperature <10 C for 3 h under constant magnetic stirring.…”
