Polymer chain dynamics: evidence of nonexponential mode relaxation using thermally stimulated depolarization current techniques.
The slowest (p=1) mode relaxation of several polyisoprenes has been experimentally isolated by thermally stimulated depolarization current techniques. Close to the glass transition the p=1 mode deviates from the exponential behavior assumed by Rouse and tube-reptation theories. This effect is found to be a consequence of the closeness of τ_{p=1} and α-relaxation time scales. The scenario resemb...
متن کاملDielectric relaxation of 2-ethyl-1-hexanol around the glass transition by thermally stimulated depolarization currents.
We explore new routes for characterizing the Debye-like and α relaxation in 2-ethyl-1-hexanol (2E1H) monoalcohol by using low frequency dielectric techniques including thermally stimulated depolarization current (TSDC) techniques and isothermal depolarization current methods. In this way, we have improved the resolution of the overlapped processes making it possible the analysis of the data in ...
متن کاملThermally Stimulated Depolarization Currents in NaCl:Ca Crystals
Analysis of the thermally stimulated depolarization currents in Ca-doped NaCl crystals is carried out by taking into account the presence of the Ca-cation vacancy complexes with vacancies in both nearest-neighbourhood and next-nearest neighbourhood position. Relaxation parameters are derived by fitting the experimental data to standard equations. The results are, where possible, compared with t...
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 کاملThermally Stimulated Relaxation and Electrical Conduction Phenomena In Polyacrylamide
Thermally stimulated relaxation (TSR), employing thermally stimulated luminescence (TSL) and thermally stimulated conductivity (TSC) as experimental techniques, in Polyacrylamide (PAA) have been studied; in the temperature range 300 480 K. Measurements of electrical conductivity () at various temperatures, in the same temperature range have been made, in both as-grown and UV-irradiated PAA fil...
