“…During the preparation of polymers, there are many ways to control the alignment of chain orientations, such as mechanical stretching, nanoscale templating, electrospinning, applying magnetic and electric field, and thermal annealing . Among them, mechanical stretching is an easy‐to‐implement and effective way to enhance the thermal conductivity of amorphous polymers.…”

The demand for flexible conductive materials has motivated many recent studies on conductive polymer–based materials. However, the thermal conductivity of conductive polymers is relatively low, which may lead to serious heat dissipation problems for device applications. This review provides a summary of the fundamental principles for thermal transport in conductive polymers and their composites, and recent advancements in regulating their thermal conductivity. The thermal transport mechanisms in conductive polymer–based materials and up‐to‐date experimental approaches for measuring thermal conductivity are first summarized. Effective approaches for the regulation of thermal conductivity are then discussed. Finally, thermal‐related applications and future perspectives are given for conductive polymers and their composites.

“…Ever-increasing demands of modern microelectromechanical systems and high-temperature electronic and energy storage devices have stimulated the research and design on multifunctional polymer composites [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. Although polymers such as polypropylene (PP) exhibit excellent processability, insulativity, and are low-cost [ 8 , 9 , 10 ], the lack of dielectric properties restricts their application in dielectric materials and electronic component fields [ 3 , 4 , 5 ]. In the meantime, dielectric ceramic/polymer composites have received special attention due to their excellent combination of processability and the high dielectric performance of polymer and ceramic [ 11 , 12 ].…”

Multifunctional polymer composites with both high dielectric constants and high thermal conductivity are urgently needed by high-temperature electronic devices and modern microelectromechanical systems. However, high heat-conduction capability or dielectric properties of polymer composites all depend on high-content loading of different functional thermal-conductive or high-dielectric ceramic fillers (every filler volume fraction ≥ 50%, i.e., ffiller ≥ 50%), and an overload of various fillers (fthermal-conductive filler + fhigh-dielectric filler > 50%) will decrease the processability and mechanical properties of the composite. Herein, series of alumina/barium titanate/polypropylene (Al2O3/BT/PP) composites with high dielectric- and high thermal-conductivity properties are prepared with no more than 50% volume fraction of total ceramic fillers loading, i.e., ffillers ≤ 50%. Results showed the thermal conductivity of the Al2O3/BT/PP composite is up to 0.90 W/m·K with only 10% thermal-conductive Al2O3 filler, which is 4.5 times higher than the corresponding Al2O3/PP composites. Moreover, higher dielectric strength (Eb) is also found at the same loading, which is 1.6 times higher than PP, and the Al2O3/BT/PP composite also exhibited high dielectric constant (εr = 18 at 1000 Hz) and low dielectric loss (tan δ ≤ 0.030). These excellent performances originate from the synergistic mechanism between BaTiO3 macroparticles and Al2O3 nanoparticles.

“…At the same time, the formation of a polymeric composite material under the influence of a magnetic field typically employs a continuous mode of treatment with a certain specified duration [8,9]. In this case, it remains to examine the influence of a magnetic field with a controlled intermittent intensity that could be derived based on the proportional-integral-differential (PID) algorithm.…”

“…An analysis of the scientific literature revealed [2][3][4][5][6][7][8][9][10][11]] that most research in the field of magnetic treatment of polymeric composites addressed rendering or changing the dielectric and magnetic properties of a material. Changing the strength indicators of a material in the formation of articles in an alternating magnetic field remains insufficiently explored.…”
