“…To illustrate, at room temperature, the multiwalled CNTs (MWCNTs) exhibit a thermal conductivity over 3000 W m −1 K −1 and a CTE of −2.5 ppm K −1 1a,146. Whereas, pure Cu has a κ of around 400 W m −1 K −1 and a CTE of 17 ppm K −1 . Several papers have comprehensively reviewed the fabrication/processing approaches, mechanical properties, tribological properties, corrosion properties, electrical properties, and applications of various MMCs .…”

This work summarizes the recent progress on the thermal transport properties of 3D nanostructures, with an emphasis on experimental results. Depending on the applications, different 3D nanostructures can be prepared or designed to either achieve a low thermal conductivity for thermal insulation or thermoelectric devices or a high thermal conductivity for thermal interface materials used in the continuing miniaturization of electronics. A broad range of 3D nanostructures are discussed, ranging from colloidal crystals/assemblies, array structures, holey structures, hierarchical structures, to 3D nanostructured fillers for metal matrix composites and polymer composites. Different factors that impact the thermal conductivity of these 3D structures are compared and analyzed. This work provides an overall understanding of the thermal transport properties of various 3D nanostructures, which will shed light on the thermal management at nanoscale.

“…As one of several potential heat-sink parts, carbon-based heat-dissipating materials such as the graphite block [6], carbon/ carbon composites [7,8], carbon/metal composites [9][10][11][12], and graphite paper [13] have been widely used because of their excellent thermal conductivity, lightweight, corrosion resistance, and high mechanical properties. To increase these properties, suitable reinforcement fillers are used with a binder (like pitch) between various carbon allotropes including graphite, carbon nanotubes, and single or multilayered graphene because of their extraordinary thermal conductivity, electrical conductivity, and mechanical properties [14][15][16][17][18]. Graphite blocks have been extensively studied as an important pitch-based heat-sink part due to its high in-plane thermal conductivity, low thermal expansion coefficient, good mechanical strength, and ultra-large specific surface area.…”

Graphite block derived from natural graphite with bimodal particle size distribution

This paper presents a novel method for the bimodal design of graphite blocks by optimizing the weight ratio of smallsized natural graphite (NG) particles (mean size of 5 μm) and large-sized NG particles (mean size of 500 μm). Graphite blocks were fabricated by subjecting a mixture containing large NG particles and a well-dispersed pitch/small-sized NG mixture (PSM) to pressure-mold heat treatment. The effect of the PSM contents on the structural, thermal, and mechanical properties of the graphite blocks was investigated. A correlation was found between the amount of small-sized NG particles, the micro-pore structure, and the distribution of large-sized NG particles. In particular, the graphite block, with small-sized NG particle content and pitch binder content of 21 wt% and 9 wt%, respectively, achieved maximum thermal conductivity and flexural strength values of 460 W m K −1 and 14 MPa, respectively, after pressure-mold heat treatment (graphitization) at 2600 °C. Our research advances the development of an eco-friendly solvent-free graphite block fabrication method that produces high-performance graphite blocks of varying size faster and more cost-effectively.

“…At present, several investigations are available on the TC of nanocomposites for graphene and CNT. [23][24][25] The distribution of reinforcement is uniform in graphene-and CNT-reinforced metal matrix nanocomposites fabricated by solid-state or other processes. Unlike grapheneand CNT-reinforced nanocomposites, during solidication, nanoparticles will redistribute and segregate in the matrix via a liquid process.…”
