Ferroelectric transitions and relaxation processes of vinylidene fluoride/trifluoroethylene copolymers
2014 Thermally Stimulated Depolarization (TSD) measurements with a superimposed piezoelectric noise allowed us to identify the ferroelectric-to-paraelectric phase transition in vinylidene fluoride/trifluoroethylene (VDF/TrFE) copolymers, with different molar ratios. A second peak was also detected in TSD measurements which maintain the ferroelectric features of the material. Long relaxation pro...
متن کاملUniversal Ferroelectric Switching Dynamics of Vinylidene Fluoride-trifluoroethylene Copolymer Films
In this work, switching dynamics of poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] copolymer films are investigated over unprecedentedly wide ranges of temperature and electric field. Remarkably, domain switching of copolymer films obeys well the classical domain nucleation and growth model although the origin of ferroelectricity in organic ferroelectric materials inherently differs ...
متن کاملEffect of electron irradiation on poly„vinylidene fluoride-trifluoroethylene... copolymers
Electrical field-induced strain response of electron-irradiated poly~vinylidene fluoride-trifluoroethylene! copolymer has been studied by a Mach–Zehnder type heterodyne interferometer in the frequency range of 3–9 kHz. The electrostrictive constant is calculated from the strain results, which is of the same order of magnitude as those obtained at 1 Hz by a bimorph-based strain sensor but at muc...
متن کاملSurface structure of ultrathin copolymer films of ferroelectric vinylidene fluoride (70%) with trifluoroethylene (30%) on graphite
The structure and local structural distortions, through the polarization manipulation, of crystalline films of ferroelectric vinylidene fluoride (70%) with trifluoroethylene (30%) [P(VDF-TrFE)] copolymer on graphite were studied by scanning tunneling microscopy (STM). A quasispiral twist in CuC bonds with rotations about the polymer chain axis was observed by high-resolution STM, indicating a s...
متن کاملLow-temperature specific heat measurement of a ferroelectric copolymer film of vinylidene fluoride and trifluoroethylene
The specific heat of a highly crystallized ferroelectric copolymer film of vinylidene fluoride (;80 mol%) and trifluoroethylene (;20 mol%) was measured over the previously unexplored temperature range from 3.7 to 8.5 K. The data show a dominant cubic temperature dependence, with only marginal evidence for a T or a T component. There is also no evidence for the discontinuity in slope that was ob...
