“…It can be seen that the thermal conductivity of PC/ABS composites increases quickly at first, and then keeps nearly constant with the increase of mass fraction of MgO. The inflection point of curve is at a small particle mass fraction of 30% with maximum thermal conductivity of 1.95 6 0.02 W mK 21 . This phenomenon is in reasonable agreement with Cumberland and Crawford's [50] theoretical calculation.…”

“…Meanwhile, the thermal conductivity of the composite with GNPs is higher than that without GNPs and increases 60% with respect to the composites without GNPs. The absolute value of thermal conductivity enhancement is 1.16 W mK 21 , much more than the value of 0.09 W mK 21 (the thermal conductivity enhancement of composite with only 0.5 wt% GNPs with respect to neat PC/ABS alloy). Based on the above results, a remarkable synergistic effect on thermal conductivity improvement of the PC/ABS composite with alumina, magnesia, and GNPs is shown in this research, and the contribution value of synergistic effect on thermal conductivity enhancement is 1.07 W mK 21 .…”

“…It can also be seen that the thermal conductivity of the composite with GNPs is higher than that without GNPs with same total mass fraction. The maximum thermal conductivities of the composites with and without GNPs are 3.11 6 0.15 and 1.95 6 0.1 W mK 21 , respectively. On one hand, the two-dimensional GNPs can bridge the alumina and magnesia particles to form more compact packing structure and provide more thermal conductive pathways.…”

“…It increases sharply with the increase of GNPs mass fraction and then declines slightly with further increase of GNPs mass fraction. The maximum thermal conductivity of PC/ABS composite is 3.11 W mK 21 at total mass fraction of 70% with 0.5 wt% GNPs. This different variation tendency of thermal conductivity depends on the disperse state of GNPs in the PC/ABS matrix.…”

“…Polymer composites combining the advantages of polymers and filler components have attracted research attention from the academic and industrial communities [8]. Highly thermal conductive inorganic fillers have been adopted for improving the thermal properties of polymer composites, such as aluminum nitride (AlN) [9][10][11], boron nitride (BN) [12,13], aluminum oxide (Al 2 O 3 ) [14][15][16][17], zinc oxide (ZnO) [18], magnesium oxide(MgO) [19], silicon carbide (SiC) [20,21], multi-walled carbon nanotubes (MWNTs) [22], and graphene nanoplatelets (GNPs) [23,24].…”

Graphene nanoplatelets (GNPs) have attracted considerable attention in the field of thermal management materials due to their unique structure and exceptional thermal conductive properties. In this work, we demonstrate a significant synergistic effect of GNPs, alumina (Al 2 O 3 ), and magnesia (MgO) in improving the thermal conductivity of polycarbonate/acrylonitrile-butadienestyrene polymer alloy (PC/ABS) composites. The thermal conductivity of the composites prepared through partial replacement of Al 2 O 3 and MgO with GNPs could increase dramatically compared with that without GNPs. The maximum thermal conductivity of the composite is 3.11 W mK 21 at total mass fraction of 70% with 0.5 wt% GNPs loading. It increases 60% compared with that without GNPs (1.95 W mK 21

Improved Thermal Conductivity of Poly(trimethylene terephthalate‐block‐poly(tetramethylene oxide) Based Nanocomposites Containing Hybrid Single‐Walled Carbon Nanotubes/Graphene Nanoplatelets Fillers

The thermal conductivity of poly(trimethylene terephthalate-block-poly(tetramethylene oxide) copolymer (PTT-PTMO)-based nanocomposites filled with the hybrid system of nanofillers, including single-walled carbon nanotubes (SWCNT) and graphene nanoplatelets (GNP) is studied. At the same loading, SWCNT provided greater thermal conductivity enhancement when added to thermoplastic elastomer matrix when compared to GNP. Moreover, SEM images showed that SWCNT and GNP were well dispersed in PTT-PTMO, suggesting that in situ polymerization is a highly efficient method for preparing hybrid nanocomposites with low loading of carbon nanofillers. To further improve thermal conductivity of PTT-PTMO-based nanocomposites, a hybrid SWCNT/GNP was used. When the ratio of SWCNT to GNP was 5:1, i.e. 0.5 wt% of SWCNT and 0.1 wt% of GNP, the PTT-PTMO-based nanocomposites exhibited the highest thermal conductivity of 0.30 W/m·K, higher than that filled with SWCNT and GNP alone. This suggests that the combination of two types of nanofillers, which differ in shape, allows obtaining the synergistic effect for the thermal conductivity enhancement of PTT-PTMO.

Construction of a vertically aligned and densely interconnected ordered 3Dfiller framework in a polymer matrix is a challenge to attain significant thermal conductivity (TC) enhancement efficiency. Fortunately, many biomaterials with unique microstructures can be found in nature. With inspiration from wood, artificial composites can be rationally designed to achieve desired properties. Herein, the authors report a facile and effective approach to fabricate anisotropic polymer composites by biotemplate ceramization technology and subsequent vacuum impregnation of epoxy resin. The hierarchical microstructure of wood is perfectly replicated in the cellular biomass derived SiC (bioSiC) framework by carbothermal reduction. Owing to the anisotropic architecture of bioSiC, the epoxy composite with vertically aligned dense SiC microchannels shows interesting properties, including a high TC (10.27 W m −1 K −1 ), a significant enhancement efficiency (259 per 1 vol% loading), an outstanding anisotropic TC ratio (5.77), an extremely low coefficient of linear thermal expansion (12.23 ppm K −1 ), a high flexural strength (222 MPa), and an excellent flame resistance. These results demonstrate that this approach is expected to open a new avenue for design and preparation of high performance thermal management materials to address the heat dissipation of modern electronics.
