In this article, we review thermal transport in polymers with different morphologies from aligned fibers to bulk amorphous states. We survey early and recent efforts in engineering polymers with high thermal conductivity by fabricating polymers with large-scale molecular alignments.

Effective medium theory calculation of polymer composite thermal conductivity with BN fillers (assumed to be isotropic) as a function of interfacial thermal conductance between the filler and the matrix. Polymer matrix with thermal conductivity of 0.15 W/mK and 1.5 W/mK are considered. Different color lines correspond to different volumetric loading fractions. A. Henry, Thermal Transport in Polymers, Annual Review of Heat Transfer, Vol 17, Chapter 13, p. 485-520 (2013) 2021-04-01 To realize their potential, higher thermal conductivity and higher strength is needed, which can be achieved to some extent by adding fillers to a polymer matrix.

A key The physics of thermal transport in polymers is important in many applications, such as in heat exchangers and electronics packaging. Even though thermal conductivity models for amorphous polymers have been reported since the 1970s, none of the published models included the chain conformation and ch … Thermal transport in such polymers is primarily influenced by bonded interactions and chain orientations relative to the direction of heat transfer. We employ molecular dynamics simulations to investigate two mechanisms to control the phonon thermal transport in PANI and PA, namely, (1) mechanical strain and (2) polymer combinations.
