“…An I D /I G ratio equal to about 1.67 was reported [53] for FLG/MgO samples with 1e8 graphene layers (mostly 2e5), which is fairly close to the present values for G193 and G208. Therefore, these results could indicate that, for G56, the carbon was deposited in forms closer to BLG than 5e10 layers graphene, which would be in agreement with using a CVD atmosphere poorer in CH 4 . However, the MgO powder grains are faceted and this could provoke the formation of defects (kinks) in the deposited FLG and thus the proportion of defects could also be higher for G56.…”

“…Using 2.1 and 3.58 g/cm 3 for the densities of graphene and MgO, respectively, the carbon content is equal to 0.56, 1.93 and 2.08 vol% for the samples prepared using 1, 2.5 and 5 L/h of CH 4 , respectively. For the sake of brevity, these powders will be denoted hereafter as G56, G193 and G208, respectively.…”

“…The matrices investigated include borides (ZrB 2 [5]), carbides (B 4 C [6], SiC [7e10], TiC [11], TaC [12,13]), nitrides (AlN [14e17], Si 3 N 4 [18e22], TiN [23]) and oxides (MgO [24], Al 2 O 3 [25e33], SiO 2 [34], ZrO 2 [35] and hydroxyapatite [36,37]). Many processing methods involve the preparation of graphene/ceramic powders followed by a consolidation step performed by a variety of techniques including pressureless sintering, spark plasma sintering, hot pressing and hot isostatic pressing.…”

“…GO may have to be reduced to partially eliminate some defects in the so-obtained reduced-graphene oxide (r-GO). As a typical example, Fan et al [28] used GO flakes prepared by a lengthy procedure involving the treatment of graphite by solutions of H 2 SO 4 and KMnO 4 (magnetic stirring, 2 h), H 2 O 2 (decantation, a few hours), washing with HCl solution, vacuum filtration (several times), dialysis for a week, sonication and centrifugation (4000 rpm for 30 min) and these authors readily admit that the elastic properties of their FLG have been deteriorated severely by oxidation and reduction. The mechanical exfoliation of graphite [41] is also used for the preparation of GNS and GNP samples.…”

Christophe Fast and easy preparation of few-layered-graphene/magnesia powders for strong, hard and electrically conducting composites. (2018) a b s t r a c tComposite powders were prepared by the chemical vapor deposition (CH 4 /Ar atmosphere) of carbon in the form of 2e8 layers few-layered-graphene (FLG) covering the MgO powder grains, without any mixing step. The composites were consolidated to nearly full (99%) density by spark plasma sintering with no or little damage to the FLG. The FLG is located along the MgO grain boundaries, as opposed to be dispersed as discrete particles or flakes. This causes a dramatic hindrance of the MgO grain growth, the average grain size being considerably lower for the sample with 2.08 vol% carbon (200 nm) than for pure MgO (3.7 mm). The samples are investigated by Raman spectroscopy, scanning and transmission electron microscopy. The composites are electrically conducting with a percolation threshold below 0.56 vol%. Compared to pure MgO, the composites are simultaneously stronger (345 vs 200 MPa) and harder (9.8 vs 3.8 GPa). This could arise from reinforcement mechanisms such as crack-deflection and crack-bridging by FLG, but also from MgO grain refinement.

“…Quite important subjects as the dispersability and stability of graphene nanostructures in solvents, and particularly for making reliable composites, have also been treated abundantly and extensive works tackled this matter [3,4]. Concentrating on ceramic/graphene composites, a notable augment of the numbers of publications on these composites is observed and even few publications reviewing these materials already exist, the early one by Porwal et al [5] and two recent review papers by Markandan et al [6] and Nieto et al [7]. The processing of graphenebased composites, with specific mention to the graphene synthesis methods and their mixing with the matrices, as well as available densification methods, have been broadly revised in these previous reviews.…”

The updated results on the relevant properties of graphene reinforced ceramic are reviewed. The representative data for a wide number of bulk composites are compared, making special emphasis on the mechanical properties (fracture toughness, strength), wear and friction characteristics, and elastic properties. The electrical functionality boosted by the contacted graphene network is critically assessed for conducting and dielectric matrices. Regarding thermal transport, the enhancement or depletion of thermal conductivity is revised considering for different matrices and for specific orientations. Furthermore, new developments on layered and coatings, as well as in cellular composites that certainly widen the scope of applications for these remarkable group of ceramic composites are looked over.

Graphene‐skinned fiber fabric is prepared by chemical vapor deposition (CVD) of continuous graphene on fabric, which enables conformal graphene coverage on fibers and inherits high electrical and thermal conductivity of graphene. However, in the fabric‐shaped configuration, high electrical and thermal contact resistances between fibers, and the lack of conductive and thermal pathways along radial direction of fibers limit the improvement of electrical and thermal conductivity. Herein, carbon nanotubes (CNTs), due to the 1D structure with excellent electrical and thermal conductivity, are introduced to build rich “bridges” to connect the isolated fibers to build new electron and phonon transport channels. Thus, the conceptual design of CNT/graphene‐skinned glass fiber fabric (CNT/GGFF) is creatively proposed and realized by a carefully designed CVD. Constructing the 3D electrically and thermally conductive network in CNT/GGFF leads to >90% decrease of sheet resistance, 4.5 times increase of tensile strength, and >70% decrease of thermal resistance compared with GGFF, making it promising for applications in composite materials, heat dissipation, and de‐icing. Moreover, the thermal resistance of CNT/GGFF exhibits temperature‐independent, extending applications to aviation and space because changes in thermal conductivity of traditional materials with environmental temperatures can adversely affect the thermal stability, reliability, and lifetime of aircrafts.
