What is Enhanced energy density of PVDF-based nanocomposites via a core–shell strategy about?
## Abstract In recent years, high energy density polymer capacitors have attracted a lot of scientific interest due to their potential applications in advanced power systems and electronic devices. Here, core–shell structured TiO~2~@SrTiO~3~@polydamine nanowires (TiO~2~@SrTiO~3~@PDA NWs) were synthesized via a combination of surface conversion reaction and in-situ polymerization method, and then incorporated into the poly(vinylidene fluoride) (PVDF) matrix. Our results showed that a small amount of TiO~2~@SrTiO~3~@PDA NWs can simultaneously enhance the breakdown strength and electric displacement of nanocomposite (NC) films, resulting in improved energy storage capability. The 5 wt% TiO~2~@SrTiO~3~@PDA NWs/PVDF NC demonstrates 1.72 times higher maximum discharge energy density compared to pristine PVDF (10.34 J/cm^3^ at 198 MV/m vs. 6.01 J/cm^3^ at 170 MV/m). In addition, the NC with 5 wt% TiO~2~@SrTiO~3~@PDA NWs also demonstrates an excellent charge–discharge efficiency (69% at 198 MV/m). Enhanced energy storage performance is due to hierarchical interfacial polarization among their multiple interfaces, the large aspect ratio as well as surface modification of the TiO~2~@SrTiO~3~
