Dielectric spectroscopy and thermally stimulated discharge current in PEEK film
The complex permittivity of films of polyether ether ketone (PEEK) has been investigated over a wide range of frequency. There is no relaxation peak in the range of 1Hz to 10 Hz but in the lowfrequency side (10 Hz) there is an evidence of a peak that also can be observed by thermally stimulated discharge current measurements. That peak is related with the glass transition temperature (T g ) of ...
متن کاملAnalysis of ice water by the thermally stimulated depolarized current (TSDC) method.
The thermally stimulated depolarized current and temperature profiles (TSDC analysis) on iced water was proved to be an effective tool for the qualitative evaluation of various water samples, each having an independent relaxation process, brought about by a pure dipolar orientation. The method proved to be applicable to different kinds of water samples used in the experiment and tap-water sampl...
متن کاملstudy of the thermally stimulated depolarization current (tsdc) for composites of acrylonitrile butadiene rubber (nbr) loaded with haf
the thermally stimulated discharge (tsdc) current is studied for acrylonitrile butadiene rubber (nbr) loaded with different high abrasion furnace carbon black (haf). tsdc peak appears only for higher haf contents > 60phr (70 and 80phr of haf contents), the tsdc spectra consist of a sharp peak corresponding to a peak temperature tm which is slightly shifted to higher temperature for 70phr ...
متن کاملModeling of Optical Waveguide Poling and Thermally Stimulated Discharge
AbsfracfA charge density and current density model of a waveguide system has been developed to explore the ef€ects of electric field electrode poling. An optical waveguide may be modeled during poling by considering the dielectric charge distribution, polarization charge distribution, and conduetion charge generated by the poling field. These charge distributions are the source of poling curren...
متن کاملThermally Stimulated Discharge Current Studies in a Polymkthyl Methacrylate Polystyrene Blend
Thermoelectrets were prepared using polymethyl raethacrylate (PMMA), polystyrene (PS) and their blend in the 50:50 weight ratio. The TSDC spectra of PMMA shows both dipolar and space charge peaks, while the TSDC spectra of PS shows only the space charge peak. The TSDC spectra of the blend however, shows only one peak which is the space charge peak. It is therefore concluded that the PMMA dipole...
