Abstract
Flexible substrates including a polymer selected from a thermoplastic polymer, a thermoset polymer, and/or a polymer blend, and ferroelectric perovskite-type oxide particles dispersed in the polymer, where the ferroelectric perovskite-type oxide has a dielectric constant that varies with applied voltage. The flexible substrates can be used in tunable electronics.
Claims21
A composite material comprising:
- a polymer selected from a thermoset polymer, and a blend of at least one thermoplastic polymer and at least one polymer with a loss tangent of less than 0.005 at 10 Ghz;
- and
- ferroelectric perovskite-type oxide particles dispersed in the polymer;
- wherein a ferroelectric perovskite-type oxide, in the ferroelectric perovskite-type oxide particles, has a dielectric constant that varies with applied voltage.
