The study by Biercuk et al. (2002) investigates the thermal and mechanical properties of single-wall carbon nanotube (SWNT)-epoxy composites. The researchers found that SWNTs significantly enhance the thermal conductivity of epoxy, with a 125% increase at 1 wt% loading compared to vapor-grown carbon fibers (VGCF), which only show a 45% increase. Electrical conductivity measurements revealed a percolation threshold between 0.1 and 0.2 wt% SWNT loading, while Vickers hardness increased monotonically with SWNT loading up to 3.5 times at 2 wt%. These results suggest that SWNT-epoxy composites offer improved thermal and mechanical properties without the need for chemical functionalization of the nanotubes. The superior performance of SWNTs is attributed to their nanoscale diameter and larger aspect ratio, which facilitate the formation of a more extensive network at the same weight loading. Future research will focus on further enhancing SWNT-matrix interactions and creating anisotropic thermal management composites.The study by Biercuk et al.
