tilted at 20掳 or higher with respect to a normal vector to a readily heat-conducting surface of the metal-graphite composite material is 15% or less relative to a whole amount of the scaly graphite powder, and the metal-graphite composite material has a relative density of 95% or higher....
The results of measurements of thermal conductivity, electric resistivity and heat capacity of graphites with density of 1·9 g/cm 3 and higher in the temperature range 50–2500°K are presented. On basis of the modified Debye equation average crystal parameters for the graphites investigated are...
The composites have higher thermal conductivity than PP/BN composites. The result suggested that the VGCF generates a thermal conductive bridge in composites to connect the BN particles in PP matrix. Such structure leads to improvement in the thermally conductive network of fillers. Graphite is ...
The ratio of C–C bonds in few-layer graphene prepared using decanal was 54.0%, which was higher than the ratio of few-layer graphene prepared using octadecanal (48.9%). This was assumed to occur because many molecules were grafted on decanal, which has a shorter alkyl chain. As shown ...
Used in conjunction with heat spreaders, it can create a higher-performing thermal design. HEAT SPREADING RATIO(Also known as “Anisotropic Ratio”) This ratio characterizes heat dissipation: kxy - Thermal conductivity in-plane divided by kz - Thermal conductivity through-plane Common heat spreader...
The basal plane cleavage energy (CE) of graphite is a key material parameter for understanding many of the unusual properties of graphite, graphene and carbon nanotubes. Nonetheless, a wide range of values for the CE has been reported and no consensus ha
A comparative analysis of the thermal conductivity values obtained in this study (parallel to the precipitation plane) and those reported in the reference sources was performed. The studied temperature range was extended into the higher temperature region by 450 K and constitutes 1900–2950 K. 展开...
This property has made the graphite suitable to use in many components which require high lubricating properties [7]. Furthermore, due to its hexagonal arrangement of carbon atoms the unhybridized p-orbitals can form an electron cloud throughout the lattice, which results in higher electrical ...
This is prepared bygrindingexpanded graphiteinto powder. It has a less compact structure than natural graphite and tends to build networks even at small concentrations. Thus compared to natural graphite, smaller amounts of expandedgraphite powderare required to reach a similarthermal conductivity. Never...
