Learn more. Flexible dielectric and electronic materials with high dielectric constant (k) and low loss are constantly pursued. Encapsulation of conductive fillers with insulating shells represents a promising approach, and has attracted substantial research efforts.
The revealed polarization mechanism and the optimization strategy for core–shell fillers provide critical guidance and a new paradigm, for developing advanced polymer dielectrics with promising property sets. The authors declare no conflict of interest.
Due to the self-passivating nature, the as-received pristine filler is coated with an amorphous oxide layer. It has been reported that these single-shell fillers can improve the dielectric properties of the polymer composites, because of the similar concept of “insulation layer over metallic core” [, , ].
As schematically depicted in Fig. 8, the fillers calcined at a low temperature are encapsulated by a dual layer of nc-Al 2 O 3 and c-Al 2 O 3, and therefore more electrons can be accumulated at these extensively expanded interfaces.
For dielectric materials used in electrostatic capacitors, polymers have intrinsic advantages over the ceramic counterparts in terms of high breakdown strength, low production cost, mechanical flexibility and self-healing behavior.
