High-ε, Low-Loss, Thermally Conductive
By combining a crystalline alumina shell with a polydopamine coating, this dual-shell structure concurrently enhances dielectric constant, breakdown strength, and thermal conductivity while suppressing dielectric loss near the percolation threshold—an achievement unattainable with pristine Al/PVDF composites.
