The development of heterostructures offers an effective method for influencing thermal transport mechanisms. This work presents the preparation heterostructured, thermally conductive alumina nanosphere@boron nitride nanosheet (f-A@B) fillers that resemble "sesame crackers" using in situ approach. Benefited from synergistic effect zero-dimensional (0D) alumina/two-dimensional (2D) boron (BNNS) which and BNNS are boned at interface, f-A@B/poly(dimethylsiloxane) (PDMS) nanocomposites presented excellent heat dissipation efficiency. uniformly connecting to interlaminar is essential supplying a conduction channel. At mass fraction 30 wt % f-A@B, f-A@B/PDMS nanocomposite optimal conductivity (κ) 3.72 W m–1 K–1, 1279% increase over pure PDMS. modified Hashin–Shtrikman (MHS) model verifies explains experimental results, suggesting reduced filler-to-filler interfacial resistance accounts construction f-A@B heterostructure. Meanwhile, as-prepared composites also exhibit exceptional volume resistivity up 2.2 × 1013 Ω cm, 4 orders magnitude greater than critical electrical insulation (109 cm). with superior insulating properties may open future opportunities packaging management.
