What is it about?
We have developed all-organic dielectric films with both high breakdown strength and high permittivity from core-shell structured poly(vinylidene fluoride)-based copolymers fibers via coaxial electrospinning combined hot-pressing approach, which has unique advantage in elaborately adjusting the compositions of each polymer and their topological distribution. The resultant gradient polarization distribution leads to a significant improved energy storage capacity. Our simulation results from molecular level to microscale collaboratively confirm that polarization distribution adjustment is an effective strategy for high-performance electrostatic energy storage.

Why is it important?
Our study demonstrates that all-organic nonlinear dielectric polymer blends are promising candidates and adjusting compositions and their topological distribution via coaxial electrospinning technique has great potential in large-scale, high-performance dielectric films fabrication towards high power capacitor application.
