“…polyvinyl chloride, styrenemethyl methacrylate copolymer, Fe-doped polyvinyl acetate, and polystyrenesulfonic acid and other films, were studied by the TSDC and other relaxation techniques [261][262][263][264][265][266][267][268]. The TSDC spectra of poly(vinyl pyrrolidone) (40 kDa) films (thickness 17.6 μm, dried in vacuum for 48 h) were studied as a function of polarising field strength (F p = 0.114-2.272 MV/m) and polarising temperature T p = 305, 317 and 323 K at a constant heating rate b = 0.14 K/s [261].…”

ABSTRACT:The electrical transport properties, such as direct current (dc) electrical conductivity ( s), dielectric constant ( 1), and dc current-time characteristics of unirradiated and g-irradiated pure and NiCl 2 -doped PVA were studied in the temperature range of 26-155ЊC. Quantitative analysis was carried out to determine the thermal activation energy of the conduction process, drift mobility, and carrier concentration. The thermally activated mobility of charge carriers is confirmed from calculations of drift mobility at different g-doses and temperatures. The results obtained revealed that g-irradiation enhances the conductivity. The dielectric constant data at different temperatures before and after irradiation can be attributed mainly to the changes in the intra-and intermolecular interactions. The dc conductivity at 30 and 40ЊC, activation energy in low temperature region I, and 1 max for 20 wt % NiCl 2 proved to be dosedependent. The obtained data suggests that these materials may have an application in dosimetry.

“…PSF is composed of phenylene units linked by three different chemical groups: isopropylidene, ether, and sulfone, as shown in Figure 1. Considerable efforts have been devoted by many researchers [6][7][8][9][10] to study the new class of polymer composites reinforced with nanosized particles or structures dispersed in polymer matrix resulting in enhanced properties. However, retaining the homogeneous dispersion of nanosized particle within the polymer matrix during the synthesis of nanocomposites is very difficult due to the strong tendency for nanoparticles to agglomerate.…”

Semiconductor reinforced polymer nanocomposite materials are of great interest nowdays. The present communication describes the reinforcement of cuprous oxide (Cu2O) within polysulfone matrices. The conversion of amorphous to crystalline phase will be determined using X-ray diffraction and FT-IR studies. The morphological investigations have been carried out employing atomic force microscopy. The optical transition has been studied using UV-Visible spectroscopy. The successful grafting of semiconductor nanosphere within the polymer matrix efficaciously increases the industrial application of polysulfone.
