High thermal conductivity thermoplastic polyurethane/boron nitride/liquid metal composites: the role of the liquid bridge at the filler/filler interface

Liquid metal as liquid bridging agent to connect heat fillers at the filler/filler interface plays a vital role to enchance thermal conductivity of polymer composite, which has a high TC of 2.64 ± 0.10 W m −1 K −1 .
