“…The theoretical λ value of graphene is approximately 5300 W/mK, representing promising application as thermally conductive films and composites [150][151][152][153][154]. Zhao and coworkers [155] successfully fabricated the poly(p-phenylene benzobisoxazole) (PBO)-based nanocomposite film (λ value of 50 W/mK in the in-plane direction) with 5 wt% thermally reduced graphene sheets (TRG).…”

With the fast-developing miniaturization and integration of microelectronics packaging materials, ultrahigh-voltage electrical devices, light-emitting diodes (LEDs), and in areas which require good heat dissipation and low thermal expansion, the investigations on the polymeric composites with highly thermal conductivities and excellent thermal stabilities are urgently required, which would be beneficial to transferring the heat to the outside of the products, finally to effectively avoid substantial overheating and prolong their working life. Our article reviews recent progress in the classification, measurement methods, model and equations, mechanisms, commonly used thermally conductive fillers, and the correlative fabrication methods for the thermally conductive polymeric composites, aiming to understand and grasp how to enhance the λ value effectively. And future perspectives, focusing scientific problems and technical difficulties of the present thermally conductive polymeric composites are also described and evaluated.

“…Achieving the uniform dispersion of graphene in metal matrix is the key challenge in the practical development of graphene/metal composites, because graphene tends to form agglomerates in the fabrication process due to its nano‐scale dimension and enormous surface area . Currently, much effort has been devoted to addressing the graphene distribution issue and some success has been attained . Ball milling still remains the most popular method to disperse graphene in different metal powders, because it is easy to operate, cost effective, and widely applicable to various metals .…”

“…The graphene‐metal interface, however, is known to be naturally weak due to the poor interface wettability originating from the large mismatch in surface tension between the graphene and metal matrix . One solution to overcome this problem is to precoat the metal/carbide coatings on the surface of graphene owing to the fairly good chemical affinity of coatings to both graphene and Cu matrix . Tang et al reported that the use of Ni‐coated RGO could improve both the graphene dispersion and the interface adhesion with Cu matrix, leading to a 94% enhancement in yield strength compared to pure Cu.…”

Strong graphene‐metal interface is of significant importance for the enhanced mechanical properties of graphene/metal composites. However, the design of robust interface for the specific graphene/Cu composites remains challenging. Here, the authors present a matrix‐alloying method for the interface optimization of reduced graphene oxide (RGO)/CuTi composites in which the Cu matrix is alloyed with a trace of Ti (0.3 at.%). It is found that a 5–20 nm thick TiC layer is in situ formed at the interface of RGO/CuTi composites, which shows a specific orientation relationship with RGO: (200)TiC//(0002)RGO[01¯1]TiC//[1¯210]RGO. The generated TiC layer dramatically enhances the interfacial bonding of RGO/CuTi composite, leading to a yield strength of 242 MPa and a tensile strength of 307 MPa at 2 vol.% RGO loading, 24 and 16% higher than those of 2 vol.% RGO/Cu composite without alloying, respectively. Therefore, the matrix‐alloying is an effective approach for enhancing the interfacial bonding and mechanical properties of graphene/Cu composites.

This study examines the role of Graphene nanoplatelets (GNPs) as a solid lubricant additive to aluminum. Pure Al and Al-2 vol % GNP pellets are sintered by Spark Plasma Sintering (SPS). Their tribological properties are evaluated by a ball-on-disk tribometer at room temperature (RT) and high temperature (200 • C). Al-2 vol % GNP composite displayed poor densification (91%) and low hardness, resulting in poor wear resistance as compared to pure Al. However GNP addition resulted in a lower coefficient of friction (COF) as compared to pure aluminum at both temperatures. The results demonstrated that GNPs contribute to reducing COF by forming a protective tribolayer. GNPs also play a unique role in reducing oxygen ingress at 200 • C. It is concluded that the packing density of a starting powder blend of Al-GNP needs to be improved by using irregular shaped aluminum powder mixed with both larger and smaller GNPs. This would result in greater densification and improve wear rate while maintaining low COF.
