Electrothermal microactuators using PVDF-TrFE
The Journal of the Acoustical Society of America, 1992There is currently application in micromachining technology for a spin-on, organic piezoelectric material that could be used for microactuation. One material that possesses these properties and is currently being studied actively is the copolymer of vinylidene fluoride and triflouroethylene, PVDF-TrFE. It has been found that this material also exhibits

Dielectric nonlinearity of PVDF–TrFE copolymer
Polymer, 2000Abstract The experimental study of small signal dielectric nonlinearity is a powerful procedure for the investigation of complex ferroelectric materials. Dielectric nonlinearity of a copolymer of polyvinylidenefluoride with trifluoroethylene, in the compositions 70/30 and 56/44 mol%, has been measured by an analysis of the harmonic spectrum of the ...

Geometry and Electronic Structure of PVDF/TrFE Copolymer
Synthetic Metals, 2003Restricted Hartree-Fock self-consistent field method was employed to study all-trans molecular chain of P(VDF-TrFE) copolymer. Defect and gauche bonds in electron doped chain of P(VDF-TrFE) were found in our calculations, which could cause the relaxor behavior in electron-irradiated P(VDF-TrFE) copolymer.

Investigation of PVDF-TrFE nanofibers for energy harvesting
2012 IEEE Nanotechnology Materials and Devices Conference (NMDC2012), 2012We have investigated the copolymer polyvinylidene fluoride, (PVDF-trifluoroethylene) for energy harvesting. Polyvinylidene fluoride (PVDF) nanofibers were electrospun on indium tin oxide (ITO) coated plastic. The electrical response of nanofibers at different frequencies was investigated.

Gold nanoparticles doped flexible PVDF-TrFE energy harvester
The 8th Annual IEEE International Conference on Nano/Micro Engineered and Molecular Systems, 2013We have successfully developed flexible thin-film energy harvesters based on gold nanoparticles doped PVDFTrFE (polyvinyledenedifluoride-trifluoroethylene) copolymer. The thin film characteristics can be well controlled by the manufacturing process involving the spin-coating and electrochemical deposition.
