| 摘要 |
In one aspect of the present invention, an article is described, including a polymer layer; and a composite layer disposed on the polymer layer. The composite layer includes a thermoplastic polymer, which contains at least one inorganic component having selected dimensions; wherein the largest dimension of the inorganic component is less than about 1 micrometer. The composite layer has a dielectric constant, which is at least about 30 percent greater than the dielectric constant of the polymer layer. The article has a breakdown strength of at least about 150 kV/mm. Related devices are also described.
