“…The TEM images of Gr/AlSi10Mg are shown in Figure 3. In Figure 3a, the Al 4 C 3 phase, which had been verified by the FFT (Fast Fourier transform) pattern in Figure 3b, was observed near the interface between Gr and the Al matrix, as reported in several articles [5,15,25]. In this experiment, high-quality monolayer graphene was used to synthesize the graphene-reinforced AlSi10Mg composite.…”

“…By using first-principle calculations, Li et al, investigated the heterogeneous nucleation interface of Al/Al 3 Ti [13] and Wang et al, examined the interfacial properties of the Mg (0002)/Al 2 MgC 2 (0001) interface [14]. It has also been shown that Al 4 C 3 might nucleate and grow on graphene, although this needs to be further confirmed [15,16]. The interaction of atoms at the interface between Gr and Al 4 C 3 has not been studied, as far as we know.…”

The Al4C3 phase was precipitated via a reaction of graphene (Gr) with Al during selective laser melting (SLM). The interfacial nature of the Gr (0001)/Al4C3 (0001) interface was determined using the first-principle calculation. The simulation results showed that the influence of the stacking site on the interfacial structure was limited and the Al-termination interface presented a more stable structure than the C-termination interface. The Al-termination-CH site interface had the largest work of adhesion (6.28 J/m2) and the smallest interfacial distance (2.02 Å) among the four interfacial structures. Mulliken bond population analysis showed that the bonding of the Al-termination interface was a mixture of covalent and ionic bonds and there was no chemical bonding in the C-termination interface.

“…The relative density of the rGO/Bi2Te3 nanocomposite bulk materials with different content of rGO was calculated by the ratio of the corresponding measured density: theoretical density. The density of Bi2Te3 and rGO used for calculated the theoretical density of the rGO/Bi2Te3 bulk material was 7.86 g/cm 3 [14] and 2.28 g/cm 3 [25], respectively. Figure 2 shows the XRD patterns of rGO/Bi2Te3 nanocomposite powders with different contents of rGO from 0 to 1 wt%.…”

Reduced graphene oxide (rGO)/Bi2Te3 nanocomposite powders with different contents of rGO have been synthesized by a one-step in-situ reductive method. Then, rGO/Bi2Te3 nanocomposite bulk materials were fabricated by a hot-pressing process. The effect of rGO contents on the composition, microstructure, TE properties, and carrier transportation of the nanocomposite bulk materials has been investigated. All the composite bulk materials show negative Seebeck coefficient, indicating n-type conduction. The electrical conductivity for all the rGO/Bi2Te3 nanocomposite bulk materials decreased with increasing measurement temperature from 25 °C to 300 °C, while the absolute value of Seebeck coefficient first increased and then decreased. As a result, the power factor of the bulk materials first increased and then decreased, and a power factor of 1340 μWm−1K−2 was achieved for the nanocomposite bulk materials with 0.25 wt% rGO at 150 °C.

“…[ 32 ] Al 4 C 3 is also an abrasive material with high hardness and high thermostability (up to 1400 °C), which can be used in high‐speed cutting tools. Besides, Al 4 C 3 formation provides an interfacial anchoring layer in Al/C (graphite, CNT, graphene derivatives) composites, which improves composite's mechanical properties such as enhancement of specific strength, fracture elongation, [ 36 ] Vickers hardness, [ 37 ] as well as the decrease of thermal expansion coefficient. [ 38 ] This material was never before reported as a product of laser processing in a graphene‐polymer composite until now.…”

Polyethylene terephthalate (PET) is the most widely used polymer in the world. For the first time, the laser‐driven integration of aluminum nanoparticles (Al NPs) into PET to realize a laser‐induced graphene/Al NPs/polymer composite, which demonstrates excellent toughness and high electrical conductivity with the formation of aluminum carbide into the polymer is shown. The conductive structures show an impressive mechanical resistance against >10000 bending cycles, projectile impact, hammering, abrasion, and structural and chemical stability when in contact with different solvents (ethanol, water, and aqueous electrolytes). Devices including thermal heaters, carbon electrodes for energy storage, electrochemical and bending sensors show this technology's practical application for ultra‐robust polymer electronics. This laser‐based technology can be extended to integrating other nanomaterials and create hybrid graphene‐based structures with excellent properties in a wide range of flexible electronics’ applications.
