Abstract

Abstract : An ultrahigh thermal conductivity ( κ = 160 W m −1 K −1 ) of thermal interface materials is achieved with a high enhancement factor (96). A small amount (2.3 vol%) of 1D multiwalled carbon nanotubes (MWNTs) with high κ constructs effective phonon transport pathways between microscale silver‐flake islands, and a solid phonon transport junction is realized by the coalescence of silver nanoparticles pre‐functionalized on the MWNTs.
