AB - Commercial thermally conductive dielectric materials used in electronic packagingtypically exhibit thermal conductivities ranging from κ ~ 0.8 to κ ~ 4.2 W m−1 K−1.Hexagonal boron nitride (h-BN) flakes are promising thermally conductive materials forthermal management of next-generation electronics. We demonstrate a cellulosebasedcomposite embedded with few-layer h-BN flakes, achieving a κ ~ 21.7 W m−1K−1, prepared using a cost-effective and scalable processing procedure. This value ismore than 5 times higher than the thermal conductivity observed in compositesembedded with bulk h-BN (κ ~ 4.5 W m−1 K−1), indicating the benefits of the superiorthermal conductivity of few-layer h-BN on the thermal conductivity of h-BN polymercomposites. When applied as a paste for thermal interface material, the few-layer h-BNcomposite can reduce the maximum temperature of a heating pad at a power densityof h = 2.48 W cm−2 by ΔTmax ~ 24.5 °C compard to bulk h-BN composites at thesame h-BN loading. Our results provide an effective approach to improve the thermalconductivity value of cellulose-based thermal pastes for thermal interface materials anddemonstrated their viability for the heat dissipation in integrated circuits and highpowerelectronic devices.
