“…The total heat flux ( q t , W m −2 ) were estimated by the eqn (2) as followed: 44 q t = λ ·Δ T · x −1 where λ is the thermal conductivity (W (mK) −1 ), x refers to the coating thickness (m), and Δ T represents the temperature difference of the coating (K). Herein, the upper surface temperature of the Cu substrate less that of the rGO or 5% AR-rGO sample was approximatively used as the Δ T .…”

“…There are several reviews regarding the thermal conductivity of graphene-polymer composites [ 13 , 14 , 15 ]. In recent years, graphene and expanded graphite have been widely studied as nanofillers for polymer composites, as thermal interface materials and heat sinks [ 16 , 17 , 18 , 19 ]. In addition to the extremely high thermal conductivity of single-layer graphene, two-dimensional morphology also makes graphene more conducive, thus improving heat transfer performance.…”

In this study, the epoxy powder was blended with graphene to improve its thermal conductivity and heat dissipation efficiency. The thermal conductivity of the graphene-loaded coating was increased by 167 folds. In addition, the emissivity of the graphene-loaded coating was 0.88. The epoxy powder was further coated on aluminum plate through powder coating process in order to study the effect on the performance of heat dissipation. In the case of natural convective heat transfer, the surface temperature of the graphene-loaded coated aluminum plate was 96.7 °C, which was 27.4 °C lower than that of bare aluminum plate (124.1 °C) at a heat flux of 16 W. In the case of forced convective heat transfer, the surface temperature decreased from 77.8 and 68.3 °C for a heat flux of 16 W. The decrease in temperature can be attributed to the thermal radiation. These results show that the addition of graphene nanoparticles in the coating can increase the emissivity of the aluminum plate and thus improving the heat dissipation.

Rising demand for reliable thermally and electrically conductive and stable, light weight, and mechanically enduring materials in architecting smart electronics has accelerated the research in engineering metal-matrix composites (MMCs). Among these, copper (Cu) and aluminium (Al) based MMCs are popular owing to high electrical conductivity, but large heat dissipation in compact electronic gadgets is still challenging. The reinforcement of Cu/Al with graphene caters to the problem of heat dissipation, strengthens mechanical endurance, and optimizes electronic and thermal conductivities as per device architecture and application. Here we systematically review the state-of-the-art Cu/Al MMCs using graphene reinforcement with enhanced electrical, thermal, and mechanical attributes for smart electronics manufacturing and discuss the fundamentals for optimising the electrical and thermal charge transport in Cu/Al MMCs through graphene reinforcement. In addition, we discuss challenges, alternate solutions, and advanced prospects of graphene reinforced Cu/Al MMCs for smart electronics manufacturing.
