In this review, we discuss thermal transport in the diﬀerent classes of anisotropic polymer ﬁbers and ﬁlms. 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. thermal transport in nanofluids Annual Review of Materials Research Vol. 34:219-246 (Volume publication date 4 August 2004) First published online as a Review in Advance on March 17, 2004 https://doi.org/10.1146/annurev.matsci.34.052803.090621 Tuning thermal transport in highly cross-linked polymers by bond-induced void engineering Debashish Mukherji and Manjesh Kumar Singh Phys. Rev. Materials 5, 025602 – Published 22 February 2021 Size-dependent thermal transport in amorphous materials is decomposed into crystalline, crystalline-to-amorphous, and amorphous regimes. In the amorphous regime, the mean free path of propagating heat carriers can range from tens of nanometers to more than 100 nm, contributing 16%--36% of the total thermal conductivity. 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.
