英文摘要With the fast development of integrated circuit devices as well as batteries with high energy densities, the thermal management of electronic components is becoming increasingly crucial to maintaining their reliable operations. Boron nitride nanosheets (BNNS), which have superhigh thermal conductivity along the in-plane direction while remaining electrically insulating, were widely regarded as an ideal filler for preparing high-performance polymer composites to address the "thermal failure" issue. However, due to the instinctive rigidity of BNNS, the nanosheets are unable to form a tightly interfacial contact between the adjoining fillers, resulting in some micro- and nanovoids within the heat transfer pathways and severely limiting further thermal conductivity enhancement for BNNS-based composites. Herein, soft and deformable liquid metal (eutectic gallium-indium, EGaIn) nanoparticles were employed to fill the gaps between the adjacent BNNS with a rational design of mass ratios of BNNS and EGaIn, leading to a strongly synergistic effect with BNNS on thermal conductivity improvement. As a result, the composite film (BNNS: 63 wt% and EGaIn: 7 wt%) employing cellulose nanofibers (CNF: 30 wt%) as the polymer matrix achieves superhigh thermal conductivity along the in-plane direction of up to (90.51 & PLUSMN; 6.71) W & BULL;m-1 & BULL;K-1, showing the highest value among the BNNS-based composites with a bi-filler system as far as we know. Additionally, the film can work as a heat spreader for the heat dissipation of high-power light emitting diodes, outperforming tin foil in cooling efficiency.
