“…Fan et al [10] noted a decrease of the percolation threshold and a higher electrical conductivity by combining CB with graphite nanoplatelets (GNP). Similar positive effects have been observed in carbon nanotube (CNT)/graphite nanoplatelet hybrids [11][12][13] and CNT/GNP/CB hybrids [14]. Furthermore, by combining CNT with CB or GNP the viscosity of the composite melt has been reported to decrease in comparison to single filler composite melt at the same filler loading [15].…”

“…This dispersion can act like a physical bridge between the GNP-rich areas in the matrix while at the same time restricts their dispersion and reagglomeration (see Figure 2). In the work by Wei et al [14] carbon nanotubes were introduced in a similar system resulting in a three-fillerhybrid composite, and an even lower percolation threshold of 0.2 wt% was reported. These effects were also attributed to the ability of the spherical CB particles and the long flexible CNTs to form effective links between the more rigid GNPs.…”

Abstract. The effect of adding carbon black on the electrical and rheological properties of graphite nanoplatelets/poly(ethylene-butyl acrylate) copolymer composites produced via melt or solution mixing was studied. By adding a small amount of low-or high-structured carbon black to the nanocomposite, the electrical percolation threshold decreased and the final conductivity (at higher filler contents) increased. The effect on the percolation threshold was significantly stronger in case of the high-structured carbon black where replacing 10 wt% of the total filler content with carbon black instead of graphite nanoplatelets reduced the electrical percolation threshold from 6.9 to 4.6 vol%. Finally, the solution mixing process was found to be more efficient leading to a lower percolation threshold. For the composites containing high-structured carbon black, graphite nanoplatelets and their hybrids there was a quite reasonable correlation between the electrical and rheological percolation thresholds.

“…By dispersing different types of carbon nanofillers or combining carbon nanofillers with inorganic fillers in a polymer matrix, a composite with multifunctional properties can be developed. There are several reports in which researchers have reported that hybrid combination of fillers can produce synergetic effects on the thermal, electrical and mechanical properties of composites [13][14][15][16].…”

This work is focused on developing an epoxy-based hybrid composite using BN and VGCNF, with the main motivation of producing thermally conducting but electrically insulating composite thermal interface materials (TIMs). Various compositions of BN/VGCNF/rubbery epoxy hybrid composites were developed by 3-roll milling. The thermal conductivity of hybrid composites increases with increasing VGCNF content and electrical conductivity decreases with increasing BN content. SEM showed that BN inclusion inhibits VGCNF contacts resulting in more electrically insulating composites. Compression testing showed that BN inclusion produced stiffer composites than those produced with VGCNFs at equivalent loading. The thermal contact resistance of 6 wt.% BN/8 wt.% VGCNF/rubbery epoxy composite was 3.36 × 10 -5 m 2 .K/W at a bond line thickness of 18 m. Thermal contact resistance measurements showed that hybrid composites can offer better interfacial thermal transport at thick bond lines and this improves with increasing VGCNF content due to increased thermal conductivity imparted by VGCNF.
