摘要： A specific region of a polylactic acid sheet is heated by a microwave. To allow the polylactic acid sheet to exhibit piezoelectricity in the thickness direction of the polylactic acid sheet, a high voltage is applied to the heated polylactic acid sheet in the thickness direction of the polylactic acid sheet, and thereby the screw axes of at least a part of the polylactic acid molecules are relatively aligned with the thickness direction. Then the polylactic acid sheet is rapidly cooled, and thereby the polylactic acid molecules are immobilized. The same step is executed for other regions of the polylactic acid sheet, and thereby piezoelectricity is imparted to a wide area of the polylactic acid sheet in the thickness direction. The resultant piezoelectric sheet is capable of exhibiting a high piezoelectricity in the thickness direction.

摘要： Disclosed is a single wall carbon nanotube (SWCNT) film electrode (FE), all-organic electroactive device systems fabricated with the SWNT-FE, and methods for making same. The SWCNT can be replaced by other types of nanotubes. The SWCNT film can be obtained by filtering SWCNT solution onto the surface of an anodized alumina membrane. A freestanding flexible SWCNT film can be collected by breaking up this brittle membrane. The conductivity of this SWCNT film can advantageously be higher than 280 S/cm. An electroactive polymer (EAP) actuator layered with the SWNT-FE shows a higher electric field-induced strain than an EAP layered with metal electrodes because the flexible SWNT-FE relieves the restraint of the displacement of the polymeric active layer as compared to the metal electrode. In addition, if thin enough, the SWNT-FE is transparent in the visible light range, thus making it suitable for use in actuators used in optical devices.

摘要： Methods for producing ferroelectric device are described. A method includes positioning an organic polymeric ferroelectric layer between two conductive materials to form a stack. The stack can be subjected to a 2-step heat treating process. The first heat treating step transforms the organic polymeric ferroelectric precursor to a ferroelectric material having ferroelectric hysteresis properties, and the second heat treating step densities the ferroelectric material to obtain the ferroelectric device. The thin film ferroelectric device can include a thin film ferroelectric capacitor, a thin film ferroelectric transistor, or a thin film ferroelectric diode.
