ESR Studies of Fast Electron Irradiated Ferroelectric Poly(Vinylidene Fluoride)
Radiation-induced functionalization of ferroelectric poly(vinylidene fluoride) was studied by ESR spectroscopy. The samples were irradiated in the high vacuum of a Van de Graaff accelerator with 1.0 MeV and 1.5 MeV electrons at room temperature and the decay of free radicals was studied after transferring the samples into the air. The samples exhibit a multicomponent ESR spectrum that can be de...
متن کاملDensity Functional Theory calculations of the ferroelectric poly(vinylidene fluoride- chlorotrifluoroethylene) copolymer, compared to those of poly(vinylidene fluoride)
The quantum mechanics calculations of the energetics and structures corresponding to the different representatives structural conformations of poly(vinylidene fluoridetrifluoroethylene) and poly(vinylidene fluoridechlorotrifluoroethylene) copolymers show that the all-trans, Tp conformation, is energetically stabilized even with a chlorine substituent. The changes in the molecular arrangement as...
متن کاملNonvolatile ferroelectric domain wall memory
Ferroelectric domain walls are atomically sharp topological defects that separate regions of uniform polarization. The discovery of electrical conductivity in specific types of walls gave rise to "domain wall nanoelectronics," a technology in which the wall (rather than the domain) stores information. This paradigm shift critically hinges on precise nanoengineering of reconfigurable domain wall...
متن کاملPreparation and characterization of poly(vinylidene fluoride)/nanoclay nanocomposite flat sheet membranes for abrasion resistance.
Membranes with more resilience to abrasive wear are highly desired in water treatment, especially for seawater desalination. Nanocomposite poly(vinylidene fluoride) (PVDF)/nanoclay membranes were prepared by phase inversion and then tested for abrasion resistance. Their material properties were characterized using Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA),...
متن کاملRevisiting the δ-phase of poly(vinylidene fluoride) for solution-processed ferroelectric thin films.
Ferroelectric poly(vinylidene-fluoride) (PVDF) has, in the past, been proposed as an ideal candidate for data storage applications as it exhibits a bistable, remanent, polarization that can repeatedly be switched by an electric field. However, fabrication of smooth ferroelectric PVDF thin films, as required for microelectronic applications, is a long-standing problem. At present, the copolymer ...
