Carbon Nanotube Array/Polymer Core/Shell Structured Composites with High Dielectric Permittivity, Low Dielectric Loss, and Large Energy Density

A carbon nanotube (CNT)/polymer composite is prepared with a CNT array using an electrospinning method and hot-pressing technology. This composite exhibits a stable high dielectric permittivity and low dielectric loss over a wide frequency range, in addition to a large energy density.
