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.

“…This phenomenon was satised by modifying the surface of CNT physically with hydrophilic materials and mechanically by applying the ultrasonic sonication waves to break down the van der Waals interaction forces, thus enhancing the nanoparticles dispersion in water. 45,50 The second mechanism basically relates to the interfacial interactions forces between the nanoparticles and water which play a major role in changing the water characteristic, thus altering its thermal properties. The third mechanism corresponds to the unique thermal properties of nanoparticles which allowing the nanouid to store the heat faster than water and reaching the maximum capacity within a shorter time and evenly distributing the heat in the water.…”

“…40,41 CNTs have shown remarkable thermal properties i.e., high thermal conductivity (2000-3000 W m À1 K À1 ), which is higher than water by 3000 times. [42][43][44][45] Accordingly, many researchers have studied the thermophysical properties of nanouids using CNTs. [46][47][48][49][50] The properties of the nanouids can be enhanced and modied to meet the application inquires by controlling the nanoparticles properties including; textural properties, morphology and topology and the nanouids concentrations and operation conditions, taking in consideration the nanouids' stability.…”

“…Besides, convection performance can be further increased through the suspension of high-thermal-conductivity nanoparticle in conventional coolant [15][16][17][18]. This innovative type of fluid is coined as nanofluid which displays an exceptional potential in increasing the convection performance [19][20][21][22] because of the intensified synergy between the heat and flow fields [23][24][25][26][27][28][29].…”

In the present study, convective flow of nanofluid in porous microchannel is analyzed by utilizing field synergy principle. The effects of porous medium embedment on the field synergy of water-Al 2 O 3 nanofluid is investigated based on locally thermal nonequilibrium model. Energy equations for both fluid and solid phases are solved analytical while the field synergy formulations based on viscous dissipative flow are developed. It is observed that the interstitial heat transfer affects the field synergy of the flow tremendously. The deviation between one-energy-equation model and two-energyequation model reduces when the field synergy of the system increases. With the embedment of porous medium, the convection performance of microchannel is enhanced due to the increased synergy between the heat and flow fields. Besides, the field synergy of the system can be further enhanced by suspending nanoparticle in conventional fluid. This study provides an auxiliary point of view on the distinctive convection performance of nanofluid flow in porous microchannel.
