“…Graphene is the thinnest two-dimensional (2D) atomic material that has immerged as a revolutionary material due to its high specific surface area, superior mechanical, electrical, optical and thermal properties. Due to its unique properties, graphene has been applied in many applications including sensors, biomedical aids and membranes [11] . On top of that, graphene is acknowledged as having superior anti-bacterial and antiviral properties due to the movement of electron towards bacteria which induces cytoplasmic efflux, decreases metabolism, affects lipid membrane, causes oxidative stress, produces reactive oxygen species (ROS) and finally destroys the bacteria [12] .…”

“…Graphene has a high specific surface area and can be closely combined with ceramic matrix, which can improve the fracture toughness of ceramic materials [ 10 , 11 , 12 ]. In recent years, graphene toughened ceramic composite materials have been widely studied [ 13 , 14 ]. For example, Wang et al [ 15 ] added WC, TiC, and graphene into Al 2 O 3 matrix to obtain Al 2 O 3 /WC/TiC/graphene composite ceramic tool materials, whose optimal indentation fracture toughness, Vickers hardness, and flexural strength reached 9.42 MPa.m 0.5 , 24.64 GPa, and 646.31 MPa, respectively.…”

In this paper, the Voronoimosaic model and the cohesive element method were used to simulate crack propagation in the microstructure of alumina/graphene composite ceramic tool materials. The effects of graphene characteristic size and volume content on the crack propagation behavior of microstructure model of alumina/graphene composite ceramics under different interfacial bonding strength were studied. When the phase interface is weak, the average energy release rate is the highest as the short diameter of graphene is 10–50 nm and the long diameter is 1600–2000 nm. When the phase interface is strong, the average energy release rate is the highest as the short diameter of graphene is 50–100 nm and the long diameter is 800–1200 nm. When the volume content of graphene is 0.50 vol.%, the average energy release rate reaches the maximum. When the velocity load is 0.005 m s−1, the simulation result is convergent. It is proven that the simulation results are in good agreement with the experimental phenomena.

“…In addition, two-dimensional graphene is more easily dispersed in the aluminum matrix than one-dimensional carbon nanotubes. In recent years, with the upgrading of graphene preparation technology and the advancement of large-scale industrialization, it has become possible for high-quality and low-cost graphene to be applied in the field of composite materials [ 8 ].…”

7075Al alloy is the preferred material for lightweight automotive applications, but the existing problem is that it is difficult to combine high strength and high toughness. This paper presents our research aimed at obtaining high strength and high toughness materials by adding a nano-phase to realize microstructure refinement. Graphene nanoplates (GNP)/7075Al composites and 7075Al alloy were prepared by a stirring casting method in the present study. In comparison to 7075Al, the tensile strength of GNP/7075Al composites was increased from 572 MPa to 632 MPa while maintaining good uniform elongation of 8% to 10%. The increased strength behavior of GNP/7075Al composites while maintaining the plasticity is discussed in terms of grain refinement and dislocation evolution by analyzing the composite microstructure and quantitatively analyzing the contributions of grain boundary strengthening, solid solution strengthening, precipitation strengthening and dislocation strengthening. GNP’s strengthening of GNP/7075Al composites is mainly attributed to the refinement of grain size and the increase of dislocation density.
