In this article, we strive to deliver a comprehensive review of the state of thermal transport in polymers. We first review recent advancements in the understanding and engineering of thermal conductivity through changing the global morphology of polymers. Specifically, we will discuss the physical origin of the high thermal conductivity in polymer chains, and how this was realized in experiments. This is followed by more

The thermal transport mechanisms in conductive polymer–based materials and up‐to‐date experimental approaches for measuring thermal conductivity are first summarized. In addition, novel thermal transport phenomenon involving divergent thermal conductivity in individual polymer chains, giant thermal rectification, has been observed. In this review, the mechanism behind thermal transport in materials, interfacial thermal transport, thermal rectification in polymers, and enhancing thermal transport of polymers are firstly addressed. A review of the strategies employed to raise the thermal conductivity of polymers is provided along with an introductory review of the physics that intrinsically allows individual polymer molecules to serve as good heat conductors.

Thermal transport in polymers a review

By copolymerization process with 3,4-ethylene di-oxythiophene (EDOT), the newly formed compound has more electron-donating 2018-09-01 · In general, single polymer chain and polymer nanofibers have much higher thermal conductivity than their bulk structure due to efficient phonon transport , . Therefore, at individual chain level, polymers such as polyethylene (PE), polyacetalene (PA), polyvinyl chloride (PVC), Teflon, etc. , have great potential to achieve high thermal conductivity. The thermal conductivity of amorphous polymers is generally low, on the order of 0.1–1.0 W m−1 K −1 ; however, polymers can be inexpensive to manufacture and they are corrosion resistant and lightweight, which makes them attractive for heat transfer applications.

Recent research has focused on enhancing the thermal conductivity of polymer composites through addition of nanofillers such as nanotubes, graphite, carbon fibers, etc. Such tools will help resolve the considerable challenges of understanding thermal transport in heterogeneous electrode stacks comprising materials in which the nature of thermal transport through phonons is not well understood at present. Such advances may lead to fundamental, thermal performance-driven improvements in Li-ion materials. The fundamental thermal transport mechanisms and recent synthesis efforts in both types of nanocomposites are reviewed.
