Structural and transport properties of PVC blend PEG doped with Mg(ClO4)2 solid polymer electrolyte

Synthesis, structural, optical and electrical characterization of Y2O3/poly(ethylene glycol)–poly(vinyl chloride) based nanocomposite solid polymer electrolytes

“…the conductivity of the studied films is thermally activated, like semiconductor materials. This behavior is considered a common feature in disordered materials 27,28 and is a result of (i) the increase in the hopping of the ions or charge carriers that occurs between the coordinating sites and local structural relaxations; 41 (ii) the higher probability of the chains of the blend or YO nanosheets/blend to get faster internal modes, which enhances the bond rotation and improves such hopping; 42 (iii) the reduction in viscosity that promotes both chain flexibility 43 and the ion or dipole motion; (iv) the increase in the segmental motion of chains, which increases the free volume 31 and consequently enhances the ion mobility.…”

“…In addition, these measurements are helpful in studying other electrical phenomena, such as relaxation behavior, polarization and charge transport mechanisms. [26][27][28][29] Dielectric constant and dielectric loss investigation The dependence of the dielectric constant ε 0 on the frequency (f ) and temperature (T) for the prepared films is shown in Fig. 9.…”

“…Many researchers 1,5,28 used conductivity measurements to assess the potential ability of the prepared films to be used in solid-state electrochemical devices, in general. Some examples are electrochemical cell fabrication, fuel cells, batteries, chemical sensors and electrochemical capacitors.…”
