Flexible films of up to 50 vol % BT powder content are produced by preparing homogeneous dispersion of the powder in the polymer solutions. The films exhibited high specific volume resistivities combined with dielectric constants of up to 51.5 at 1 kHz. Low-voltage OFETs with ferroelectric hysteresis and good memory retention properties were demonstrated by using the composite films. © 2007 American Institute of Physics.en0003-695120078American Institute of PhysicsTechnology::621: Applied Physics::621.3: Electrical Engineering, Electronic EngineeringJournal Article10.1063/1.2591314Journal Article
