Abstract
The dielectric polymer materials are composed of about 25 to 90 mol % of vinylidene fluoride, about 5 to 70 mol % of ethylene trifluoride, and about 1 to 13 mol % of ethylene chloride trifluoride. The dielectric polymer materials possess a high dielectric constant and do not vary in dielectric constants with temperatures.
