“…In such structures, graphene flakes (GFs) can be considered as an intact network which leads to the increase in shear stress. [16][17][18] It was already shown that graphene networks like CG can increase the strength of the metal matrix and simultaneously, composite remains good tensile ductility. [19,20] Previously, composites were successfully obtained based on CG and molybdenum oxide, [21] CG and carbon nanotubes (CNT), [22] CG and Ni, [15] graphene network and Cu, [16][17][18] etc.…”

The incorporation of metal nanoparticles into novel carbon structures, such as crumpled graphene (CG), is a promising way to obtain a composite with better mechanical properties. Molecular dynamics simulation is used to investigate the deformation behavior of Ni–graphene composites, obtained by high‐temperature treatment, under uniaxial tension. The effect of temperatures between 1000 and 2000 K as well as the effect of nanoparticle size and anisotropy of the structure on the mechanical properties of the composite are studied. It is found that temperature from 1000 to 2000 K slightly affects the process of composite formation under hydrostatic compression. During the elastic regime of tension of the composite, the same values of Young's modulus are found for structures obtained at different temperatures. However, the ratio of nickel and carbon atoms considerably affects the mechanical properties under uniaxial tension: the less the number of Ni atoms, the higher the composite strength. Two of the three considered morphologies demonstrate close Young modulus and high strength. It is shown that the important advantage of the proposed structure is its homogeneity, which results in almost isotropic deformation. The obtained results open new prospects in using CG for composite fabrication.

“…We achieved this integration without the use of thermal annealing or high pressure as recently reported for 3D graphene‐Cu networks. [ 68 ] Besides the energy‐efficiency benefits, the spatial patterning capabilities are an additional plus that makes our method attractive for electronics implementation and other applications, including temperature sensors (Figure S24, Supporting Information). Beyond the photothermal and mechanical benefits from Al NPs, we further exploit their photonic properties in the photocatalytic oxidation of TMB.…”

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.

“…On the contrary, if the wettability between nanophases and molten metals/alloys is bad, nanophases are easily sintered or agglomerated, due to the hightemperature Brownian motion. In these cases (e.g., Cu with grapheme [60], Al with Al 2 O 3 [61], etc. ), the ball milling method using powder metallurgy would be important to obtain high-quality MMNCs [14,33], as shown in Fig.…”

Metal matrix nanocomposites in tribology: Manufacturing, performance, and mechanisms

et al. 2022

Metal matrix nanocomposites (MMNCs) become irreplaceable in tribology industries, due to their supreme mechanical properties and satisfactory tribological behavior. However, due to the dual complexity of MMNC systems and tribological process, the anti-friction and anti-wear mechanisms are unclear, and the subsequent tribological performance prediction and design of MMNCs are not easily possible: A critical up-to-date review is needed for MMNCs in tribology. This review systematically summarized the fabrication, manufacturing, and processing techniques for high-quality MMNC bulk and surface coating materials in tribology. Then, important factors determining the tribological performance (mainly anti-friction evaluation by the coefficient of friction (CoF) and anti-wear assessment with wear rate) in MMNCs have been investigated thoroughly, and the correlations have been analyzed to reveal their potential coupling/synergetic roles of tuning tribological behavior of MMNCs. Most importantly, this review combined the classical metal/alloy friction and wear theories and adapted them to give a (semi-)quantitative description of the detailed mechanisms of improved anti-friction and anti-wear performance in MMNCs. To guarantee the universal applications of these mechanisms, their links with the analyzed influencing factors (e.g., loading forces) and characteristic features like tribo-film have been clarified. This approach forms a solid basis for understanding, predicting, and engineering MMNCs’ tribological behavior, instead of pure phenomenology and experimental observation. Later, the pathway to achieve a broader application for MMNCs in tribo-related fields like smart materials, biomedical devices, energy storage, and electronics has been concisely discussed, with the focus on the potential development of modeling, experimental, and theoretical techniques in MMNCs’ tribological processes. In general, this review tries to elucidate the complex tribo-performances of MMNCs in a fundamentally universal yet straightforward way, and the discussion and summary in this review for the tribological performance in MMNCs could become a useful supplementary to and an insightful guidance for the current MMNC tribology study, research, and engineering innovations.
