“…4−6 Therefore, high thermal conductivity is urgently needed for the polymeric composites to be applied in the fields of packaging, electronics, and thermal management. 7 To date, to meet the high thermal conductivity requirements, the direct addition of a high loading of thermal conductive filler (about 20−60 vol %) into the polymer is usually necessary, which will, in turn, result in the deterioration of other properties of the resultant polymeric composites such as mechanical properties, electrical insulation, water resistance, and so on. 8,9 Obviously, conventional direct-addition methods are hard to use to fully implement the improvement of thermal conductive filler.…”

A 3D graphene network was constructed in polyamide 6 (PA6) monomers through the reduction and self-assembly of graphene oxide (GO), and then PA6 nanocomposites with low graphene content were fabricated through in situ polymerization. The effects of the 3D graphene network on the structure and properties of the PA6 were systematically investigated. Results show that the 3D graphene network can significantly improve the thermal conductivity of PA6. In the case of the PA6 with only 0.25 wt % graphene, its thermal conductivity is 0.69 W/(m K), about 2.88 times of that of the pure PA6. This improvement is attributed to the more-compact thermal conductive paths of the 3D graphene network, and its stronger interfacial interaction with PA6 in this work compares with those of pre-synthesized free-standing 3D graphene networks. Moreover, the mechanical properties and water resistance of PA6 also have significantly improved with the incorporation of the 3D graphene network.

“…Graphite has been the material most rigorously studied to understand its thermal properties and provides references to study the thermal behavior of nanostructured materials [8]. A large number of composites containing a carbon phase with enhanced thermal conductivities have been recently investigated as promising materials in this sense [9][10][11][12].…”

Thermal conductivity of Fe graphitized wood derived carbon

Graphitic porous carbon materials from pyrolysis of wood precursors were obtained by means of a nanosized Fe catalyst, and their microstructure and electrical and thermal transport properties investigated. Thermal and electrical conductivity of graphitized carbon materials increase with the pyrolysis temperature, indicating a relationship between the degree of graphitization and thus in crystallite size with transport properties in the resulting carbon scaffolds. Evaluation of the experimental results indicate that thermal conductivity is mainly through phonons and decreases with the temperature in Fe-catalyzed carbons suggesting that due to defect scattering the mean free path of phonons in the material is small and defect scattering dominates over phonon-phonon interactions in the range from room temperature to 800ºC.

“…Therefore, such materials have been applied to a wide range of fields, ranging from the civil/military aviation space industry to the automobile industry, as well as in sports, where lightweight materials are essential [7,8,9,10,11,12]. However, thermoplastic resins with low thermal conductivity limit the commercialization of the CFRP as a polymer matrix for composites [13,14]. Composites with low thermal conductivity do not dissipate heat quickly but accumulate heat, which causes deterioration of the mechanical properties due to peeling between the carbon fiber and the polymer matrix of the composite.…”

Improving the Vertical Thermal Conductivity of Carbon Fiber-Reinforced Epoxy Composites by Forming Layer-by-Layer Contact of Inorganic Crystals

A carbon fiber-reinforced polymer (CFRP) is a light and rigid composite applicable in various fields, such as in aviation and automobile industry. However, due to its low thermal conductivity, it does not dissipate heat sufficiently and thus accumulates heat stress. Here, we reported a facile and effective strategy to improve the through-thickness thermal conductivity of CFRP composites by using a layer-by-layer coating of inorganic crystals. They could provide efficient heat transfer pathways through layer-by-layer contact within the resulting composite material. The high thermally conductive CFRP composites were prepared by employing three types of inorganic crystal fillers composed of aluminum, magnesium, and copper on prepreg through the layer-by-layer coating process. The vertical thermal conductivity of pure CFRP was increased by up to 87% on using magnesium filler at a very low content of 0.01 wt %. It was also confirmed that the higher the thermal conductivity enhancement was, the better were the mechanical properties. Thus, we could demonstrate that the layer-by-layer inclusion of inorganic crystals can lead to improved through-thickness thermal conductivity and mechanical properties of composites, which might find applications in varied industrial fields.
