Ultrahigh thermal conductivity enhancement in polymer insulating materials by constructing 3D BN nanosheet networks

摘要

Novel epoxy nanocomposites are fabricated by using 3D interconnected boron nitride nanosheets (BNNSs). The nanocomposites exhibit ultrahigh thermal conductivity enhancement and suppressed dielectric loss at low BNNS loading. Furthermore, the obtained nanocomposites have high electrical insulation performance, showing potential applications in high power LED, advanced packaging materials and microelectronic devices.
