Graphene holds great potential in metal matrix composites for thermal management due to its excellent thermal properties. However, the graphene/metal composites possessing both high thermal conductivity (TC) and low coefficient of thermal expansion (CTE) have not yet been realized.
The microstructure, thermal conductivity and dielectric constant of SPS AlN samples are examined. Results show that SPS can fabrie samples with superior thermal properties. Addition of 1 wt.% CaF 2 was found to have expedited the sintering process and this yielded thermal conductivity of …

In this letter, we show that graphene, i.e., individual sheets of sp2-hybridized carbon bound in two dimensions,7–9 exhibits an extremely high thermal conductivity and long phonon mean free paths MFP . The letter provides details of
2009-4-3 · the near room-temperature (RT) thermal conductivity of partially suspended single-layer graphene is in the range K ~ 3000 – 5000 W/mK depending on the graphene flake size. The strong width dependence was also observed [4, 6]. The first experimental report of the thermal conductivity of graphene stimulated a body of theoretical work on the
2017-10-20 · High thermal conductivity of 300–900 W/m K for Cu/Dia composites, by incorporation of 40–90 vol.% diamond particles can be obtained by several fabriion routes
2011-1-1 · Every university student becomes familiar with the concept of thermal conductivity, a fundamental physical property of materials, through his or her textbooks. Initial work on high thermal conductivity was carried out in 1911 by Eucken, who discovered that diamond was a reasonably good conductor for heat at room temperature.

2015-3-9 · II.Thermal properties of graphene and few-layer graphene Graphene consists of a single layer of sp2 bonded carbon atoms packed in honey co lattice. In addition to its unique optical  and electronic properties [29, 30], graphene has demonstrated extremely high thermal conductivity [26, 27]. The thermal conductivity of graphene was measured,
High‐resolution transmission electron microscopy revealed two different SiC‐SiC boundaries, that is, amorphous and clean boundaries, in addition to a fully crystallized junction phase. A high thermal conductivity was attributed to a low lattice oxygen content and the presence of clean SiC‐SiC boundaries.
