Abstract: Polymer-based thermal interface materials play an important role in the heat removal and thermal management of high-density integrated circuits. Here, we introduce the theoretical and experi- mental progress of the thermal conductivity of polymers. Main foci are given to enhancement of thermal conductivity in polymers, including stretched polymer and polymer-based nanocompos- ites. Bottlenecks and challenges in this eld are also comprehensive discussed in this review.

Key words: polymer; polymer-based thermal interface materials; high thermal conductivity; polymer nanocomposites
