Improved dielectric constant and breakdown strength facilitates excellent energy storage density of polymer dielectrics, which is positive to miniaturize dielectric capacitors in electronic and electrical systems. Although coating polar substances on nanoparticles enhances the dielectric constants of polymer nanocomposites, it usually causes local electric field concentration, leading to poor breakdown strength. Here, fluoropolymers with tailorable fluorine content (PF0, PF30 and PF60) are coated on BaTiO (BT) nanoparticles to construct typical core-shell structures that are further blended with poly(vinylidenefluoride--hexafluoropropylene) (P(VDF-HFP)) to obtain BT@PF/P(VDF-HFP) nanocomposites.

- Integrating high-loading dielectric nanoparticles, like barium titanate (BT), into polar polymer matrices can significantly enhance the dielectric properties of polymer nanocomposites, but challenges exist in dispersing the nanoparticles effectively.
- This study presents a new method using "thiol-ene click" and isostatic pressing to create barium titanate/fluorinated silicone rubber (BT/FSR) nanocomposites with 82-90 wt% BT that maintain good dispersion and compatibility.
- The resulting 90 wt% BT/FSR nanocomposite achieves a high dielectric constant of 57.8 at 10 Hz and a low loss tangent under 0.03, outperforming other combinations in breakdown strength,
