| 英文摘要 | High-performance electrostatic capacitors are in urgent demand owing to the rapid development of higher power electronic applications. However, developing polymer-based composite films with both a high breakdown strength (E-b) and dielectric constant (epsilon(r)) is still a huge challenge. Here, hierarchically structured SrTiO3@SrTiO3 nanofibers (ST@ST NFs), in which crystalline SrTiO3 nanoparticles are embedded into the amorphous SrTiO3 nanofibers, are incorporated into the poly(vinylidene fluoride-co-hexafluoropropene) (P(VDF-HFP)) matrix to form a multiscale internal/external interface to break the paradox of a high epsilon(r) with decreased E-b, and that in turn gives rise to a remarkably improved energy storage capability. The percolation of the SrTiO3-SrTiO3 interfaces could promote interfacial polarization, resulting in a substantially increased epsilon(r) of the polymer nanocomposites at a rather low concentration of nanofillers. More importantly, the improved E-b of 630 MV m(-1) is also achieved through the multiscale internal/external interface. These very favorable values give rise to an ultrahigh discharged energy density (U-d) of similar to 25.26 J cm(-3), which is 283% of the value of the pure P(VDF-HFP) film. A record enhancement ratio of U-d is achieved in this work among the previously reported results to the best of our knowledge. This approach provides a new dimension of interface engineering to adjust and improve the energy storage properties of polymer nanocomposites. |
