Abstract To efficaciously decrease dielectric loss while still synchronously harvesting a high constant ( ε ′) and breakdown strength E b ), as well good mechanical properties in silicon (Si)/poly(vinylidene fluoride) (PVDF), this work, the core@shell structured Si@silicon dioxide (SiO 2 ) particles were first prepared via temperature oxidation, subsequently incorporated into PVDF to generate morphology‐dependent composites with high‐ ′ but low loss. The SiO shell effects on morphology,...

To enhance the toughness and electrical insulation properties of cured epoxy, carboxyl-terminated polybutadiene (CTPB) liquid rubber was used to modify epoxy in this study, thermal conductivity, mechanical dielectric modified were investigated. The results indicate that CTPB-epoxy exhibits higher impact strength lower constant loss compared with pure epoxy. Further, hexagonal boron nitride (hBN) reinforce 20 phr CTPB. It is found hBN/epoxy under same filler loading, heat conductive...

Insulating interlayer between nanoparticles and polymer matrix is crucial for suppressing the dielectric loss of composites. In this study, titanium carbide (TiC) particles were surface modified by polydopamine (PDA), obtained PDA@TiC powders used to reinforce thermoplastic polyurethane (TPU). The results indicate that homogenously dispersed in compared with pristine TiC, PDA@TiC/TPU composites show improved mechanical properties, i.e., much lower dissipation factors obviously enhanced...

Abstract Polymers with high thermal conductivity (TC) and dielectric constant ( ε ) but low loss show enormously potential applications in electrical power systems. To enhance the TC while significantly suppressing of β‐silicon carbide whisker (β‐SiC w )/polyvinylidene fluoride (PVDF), this study, SiO 2 shells different morphologies were constructed on superficies β‐SiC via a facile oxidation method air atmosphere. The shell’ morphology performances @ /PVDF are systematically explored as...
