The development of thermal conduction polymer-based composites is important to solve the heat dissipation electronic instruments under overheating conditions. construction conductive pathways in and reduction contact resistance between fillers are crucial for concerning excellent properties. Herein, oriented coherent network successfully developed via situ growth carbon nanotubes (CNTs) into boron nitride nanosheets (BNNSs) skeleton prepared from ice-templated. conductivity reaches 3.21 W m−1 K−1 approximately low filler loading 9.86 vol%, due formation covalent bonding CNTs BNNSs as reducing by one order magnitude. More importantly, non-equilibrium molecular dynamics (NEMD) simulations carried out demonstrate influence elevating BNNSs. Meanwhile, volume resistivity up 1015 Ω cm far met requirement electrical insulation. This study provided a valuable idea design management materials potential applications integrated circuits.
