Dielectric Relaxation Spectroscopy and AC Conductivity of Doped Poly (Vinyl Alcohol)
The dielectric properties and AC conductivity of pure and doped PVA samples with different concentrations of CuCl2 and Thiourea are investigated in the frequency range from 0.2 Hz to 100 kHz within a temperature range from room temperature to 433 K. It is observed that the dielectric constant decreases with an increase of frequency for all samples. The behaviour of the dielectric loss (ε'') as ...
متن کاملPhotorefractive dark conductivity in Cr-doped strontium barium niobate.
We present the theoretical and experimental results of photorefractive two-beam coupling in Cr-doped strontium barium niobate:60, using thermal excitation (i.e., dark conductivity) to model the experimentally observed temperature-dependent behavior of the two-beam coupling constant and response time.
متن کاملCrosslinked Chitosan/Poly(Vinyl Alcohol) Blends with Proton Conductivity Characteristic
A quitosana é um polissacarídeo natural obtido a partir da reação de desacetilação da quitina, sendo o polímero natural mais abundante, que apresenta propriedades químicas e físicas atrativas, como por exemplo, as requeridas para obtenção de membranas poliméricas. Neste trabalho a quitosana em solução de ácido clorídrico foi quimicamente modificada com ácido sulfosuccínico (SSA), o qual reticul...
متن کاملEnhanced electrical conductivity properties of Graphene Oxide nanocomposites functionalized with Polyvinyl Alcohol
We report the synthesized and preparation of graphene oxide (GO) nanocomposite functionalized with polyvinyl alcohol (PVA) with different concentration of graphene oxide 0, 1, 1.5, 2, 2.5, 3, 3.5 and 4% weight. This synthesized confirmed by FT-IR. The electrical conductivity of the all nanocomposite was measured at 25°C for all samples and the resulted showed electrical conductivity ...
