Abstract
A multilayered dielectric film includes a plurality of nanolayers, with at least one first type of layer including traditional dielectric films and at least one second type of layer including high heat stability polymers. The consultant layered film demonstrates an improved storage modulus and decreased dissipation factor at high temperatures. The at least one first type of layer and the at least one second type of layer differ in dielectric permittivity by a factor of between approximately 0.5 and approximately 1.5 times.
