ABSTRACT:
A ferroelectric random copolymer consisting essentially of about 65 to 80 mole percent of vinylidene fluoride and 35 to 20 mole percent trifluoroethylene with an increased Curie temperature obtained via a heat-treatment within certain temperature ranges. The heat-treatment can be isothermal or cyclic. The resulting material can be used in nondestructive devices over a wider temperature range than conventional materials.
