“…These polymers have been utilized in a host of electronics including lasers, capacitors, resistors, inductors, low-loss dielectric, and wave-guide where toughness and high temperature resistance are essential. With escalating demand for lowcost interfacial materials capable of effective heat dissipation in electronic systems, nanoparticles such as GNPs and CNTs have been incorporated into polymers to form nanocomposites (Pradhan et al 2009, Harish et al 2015, Song et al 2015, Cui et al 2016. The expected specific area of application determines the choice of a particular polymer.…”

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.

“…As seen in the Table 4 There are several theoretical and empirical models to predict the thermal conductivity of two-phase composites [42]. Harish et al [43,44] analyzed experimental thermal conductivity results based on the modified effective medium theory (EMT) model. The EMT model calculations show that the thermal conductivity enhancement is highly sensitive to the thermal interface resistance and the particle aspect ratio more than the thermal conductivity of particle itself.…”

“…Many nanomaterials such as Al 2 O 3 , SiO 2 , CuO, carbon nanohorns, single-walled carbon nanotubes, multi-walled carbon nanotubes, graphene nanoplatelets (GnPs), expanded graphite and carbon nanofibers, etc., were investigated by the researchers to increase the thermal conductivity and heat transfer rate. Among these, GnPs have excellent potential to enhance the thermal conductivity to a higher level because of their two-dimensional planar structure [15][16][17][18]. The problem associated with the utilization of GnPs is agglomeration and sedimentation over the course of time.…”

In this work, we experimentally investigated the solidification behavior of functionalized graphene-based phase change nanocomposites inside a sphere. The influence of graphene nanoplatelets on thermal transport and rheological characteristics of the such nanocomposites were also discussed. We adopted the covalent functionalization method to prepare highly stable phase change nanocomposites using commercially available phase change material (PCM) OM08 as the host matrix and graphene nanoplatelets (GnPs) with 0.1, 0.3, and 0.5 volume percentage as the nano inclusions. We report a maximum thermal conductivity enhancement of ~102 and ~46% with 0.5 vol% in the solid and liquid states, respectively. Rheological measurements show that the pure PCM shows Newtonian behavior, whereas the inclusion of GnPs leads to the transition to non-Newtonian behavior, especially at lower shear rates. Viscosity of the nanocomposite increases with an increase in the volume fraction of GnP. For 0.5 vol% of GnPs, maximum increase in viscosity was found to be ~37% at a shear rate of 1000 s−1. Time required for complete solidification decreases with the loading of GnPs. Maximum reduction in solidification time with 0.5 vol% of GnPs was ~40% for bath temperature of −10°C.
