“…Maxwell-Eucken assumes that filler particles are homogeneously distributed in the polymer matrix, non-interacting, and roughly spherical. Fewer filler particles would be covered by the polymer and dispersed in the form of isolated islands in the matrix:where V f is the volume fraction of the filler, and λ c , λ f , and λ p is the thermal conductivity of composites, filler, and matrix, respectively 31, 32 . In this paper, the value of λ f and λ p used 6.032 W m −1 K −1 and 0.315 W m −1 K −1 , respectively.…”

Iron Oxide (Fe3O4) nanoparticles were deposited on the surface of low density polyethylene (LDPE) particles by solvothermal method. A magnetic field was introduced to the preparation of Fe3O4/LDPE composites, and the influences of the magnetic field on thermal conductivity and dielectric properties of composites were investigated systematically. The Fe3O4/LDPE composites treated by a vertical direction magnetic field exhibited a high thermal conductivity and a large dielectric constant at low filler loading. The enhancement of thermal conductivity and dielectric constant is attributed to the formation of the conductive chains of Fe3O4 in LDPE matrix under the action of the magnetic field, which can effectively enhance the heat flux and interfacial polarization of the Fe3O4/LDPE composites. Moreover, the relatively low dielectric loss and low conductivity achieved are attributed to the low volume fraction of fillers and excellent compatibility between Fe3O4 and LDPE. Of particular note is the dielectric properties of Fe3O4/LDPE composites induced by the magnetic field also retain good stability across a wide temperature range, and this contributes to the stability and lifespan of polymer capacitors. All the above-mentioned properties along with the simplicity and scalability of the preparation for the polymer nanocomposites make them promising for the electronics industry.

“…By electrospinning technology, the polymer chains are changed from the random arrangement to ideal single crystal nanofibers, a benefit for obtaining an extremely high λ value. In addition, some special structural monomer by chemical synthesis can also be performed to fabricate polymers with high λ value, such as PA, PANI, and PPy [114], mainly depending on conjugated π bond, to realize thermal conduction through electron conduction mechanism. Kurabayashi [115] reported the thermal conductivities and mechanisms of polyvinyl chloride (PVC), polymethyl methacrylate (PMMA), polycarbonate Fig.…”

With the fast-developing miniaturization and integration of microelectronics packaging materials, ultrahigh-voltage electrical devices, light-emitting diodes (LEDs), and in areas which require good heat dissipation and low thermal expansion, the investigations on the polymeric composites with highly thermal conductivities and excellent thermal stabilities are urgently required, which would be beneficial to transferring the heat to the outside of the products, finally to effectively avoid substantial overheating and prolong their working life. Our article reviews recent progress in the classification, measurement methods, model and equations, mechanisms, commonly used thermally conductive fillers, and the correlative fabrication methods for the thermally conductive polymeric composites, aiming to understand and grasp how to enhance the λ value effectively. And future perspectives, focusing scientific problems and technical difficulties of the present thermally conductive polymeric composites are also described and evaluated.
