  "abstract": "The rapid advancement of fifth-/sixth-generation (5G/6G) telecommunications and high-density packaging has intensified the power-density crisis, creating a critical trade-off between thermal management and ultra-low dielectric requirements for substrate materials. Herein, we propose a controllable assembly strategy integrating polycarbonate (PC)-assisted ball-milling exfoliation with non-solvent-induced phase separation (NIPS). PC chains non-covalently exfoliate hexagonal boron nitride (h-BN) into boron nitride nanosheets (BNNS; average lateral dimension ∼636 nm, thickness ∼2.0 nm, 3–7 layers) while simultaneously functionalizing the surface. A one-step volatile phase separation in a dichloromethane/isopropanol dual-solvent system constructs porous aerogel membranes featuring a dual-network architecture: an interpenetrating porous scaffold with pore-wall thermal-conductive networks. At 30 wt% BNNS loading, the composite membrane achieves in-plane and through-plane thermal conductivities of 0.30 and 0.25 W m−1 K−1, respectively, representing a threefold enhancement over pristine PC aerogel. Concurrently, the dielectric constant reaches 1.25 at 106 Hz with a loss tangent of 0.009, and the tensile stress of 12.55 MPa ensures mechanical integrity. By decoupling thermal transport through pore-wall BNNS percolation networks from dielectric response via air-phase dilution, this strategy enables concurrent high thermal conductivity, ultra-low permittivity, and robust mechanical performance in a lightweight thermoplastic platform.",
