"Ultrahigh Energy Density in Continuously Gradient-Structured All-Organ" by Yanda Jiang, Jian Wang et al.
High-performance dielectric capacitors are critical for advanced electronics and electrical power systems. Polymeric dielectrics have been widely investigated for using in dielectric capacitors because of their high dielectric constants, flexibility, low density, and easy processability. However, it is still challenging to achieve simultaneous improvements in both energy density and efficiency in these dielectric polymers. Here, we report ferroelectric polyvinylidene-fluoride-based all-organic dielectric polymer films with continuous compositional gradient structure are reported by modulating ...
