“…No clear percolation threshold was found. This behavior has been already observed by other authors [4,17]. The thermal conductivity is based on phonon transport and therefore it depends on both the filler and matrix, which contribute to the heat flow In this case, the thermal conductivities of the filler (-3000 W/ mK) and matrix (-0.1 W/mK) are very different.…”

Self-heating of conductive nanofilled resins due to the Joule effect is interesting for numerous applications, including computing, self-reparation, self-post-curing treatment of resins, fabrication of adhesive joints, de-icing coatings and so on. In this work, we study the effect ofthe nature and amount of graphitic nanofiller on the self-heating of epoxy composites.The addition of graphitic nanofillers induced an increase in the thermal conductivity ofthe epoxy resins, directly proportional to the nanofiller content. Percolation was not observed because ofthe heat transport through phonons. In contrast, the electrical conductivity curves present a clear percolation threshold, due to the necessity of an electrical percolation network. The electrical threshold is much lower for composites reinforced with carbon nanotubes (CNTs, 0.1 wt.%) than for the resin filled with graphene nanoplatelets (GNPs, 5 %). This fact is due to their very different specific areas.The composites filled with CNTs reach higher temperatures than the ones reinforced with GNPs, applying low electrical voltage because of their higher electrical conductivity. In contrast, the self-heating is more homogeneous for the GNP/epoxy resins due to their higher thermal conductivity. It was also confirmed that the self-heating is repetitive in several cycles, reaching the same temperature when the same voltage is applied.M S. G. Prolongo

“…Gojny et al [13] demonstrated the influence of the type of carbon nanotube (single-walled carbon nanotubes, double-walled carbon nanotubes and multi-walled carbon nanotubes) on the thermal conductivity of polymer composites. Gu et al [14] introduced methanesulfonic acid/gamma-glycidoxypropyltrimethoxysilan (MSA/KH-560) to functionalize the surface of GNPs. The KH-560 molecules have been successfully grafted onto the surface of GNPs to fabricate GNPs/bisphenol-A epoxy resin (GNPs/E-51) nanocomposites.…”

“…The effective transfer of heat in modern medical devices, photonics, optoelectronics, computer/electronics, and integrated circuits (ICs) has become crucial for superior reliability and performance of these devices (Miranda and Yang 2015, Nomura et al 2015, Regner et al 2016, Gu et al 2016. The rapid escalation of power densities in three-dimensional (3D) integration and highpower density communication, information, and energy storage devices has made thermal management of these devices critically essential (Renteria et al 2015a).…”

Due to escalating power densities in electronics, information, communication, energy storage, aerospace, and automobile technologies, heat dissipation has become immensely essential for the efficient performance and reliability of photonic, electronics, optoelectronics, and other devices in order to proactively prevent premature failure due to overheating. The functionalization and synergistic inclusion of thermally conducting nanoparticles such as carbon derivatives and metallic and ceramic fillers into polymer matrices have resulted in development of thermally conducting polymer nanocomposites. This has enlarged the scope of application of these materials in areas hitherto restricted due to poor thermal conductivity and, therefore, opened broad windows of opportunities for polymer nanocomposites as emerging alternative replacements for metal components in various applications where effective heat dissipation is compulsory for device performance. Thus, this paper critically discusses globally emerging technologies applied in the development of thermally conductive polymer nanocomposites for various industrial applications.
