“…Figure 7 shows that E a (film) decreases with increasing sorbitol concentration. It should be noted that the values of the activation energy in this study are lower than those in our earlier study28 on PVA doped with 1‐methyl‐3‐ n ‐decylimidazolium bromide. The effect of plasticizers on the polymer segmental and conductivity depends on the specific nature of the plasticizer, including viscosity, dielectric constant, and polymer–plasticizer interaction.…”

“…As shown in Figures 4 and 5, the impedance plots reveal second semicircles at low frequency with increasing temperature as well as concentration of sorbitol, indicating the double‐layer response at the electrode/sample interface. Thus, each sample with two semicircles can be represented by two pairs of parallel RC circuits connected into series 28. The low‐frequency semicircles indicate the capacitive nature of the interface and the low electronic conductivity in the cell 29.…”

Solid polymer membranes from poly(vinyl alcohol) (PVA) and poly(acrylamide‐co‐acrylic acid) (PAA) with varying doping ratios of sorbitol were prepared using the solution casting method. The films were examined with Fourier transform infrared spectroscopy, thermogravimetric analysis, differential scanning calorimetry, and AC impedance spectroscopy. The impedance measurements showed that the ionic conductivity of PVA–PAA polymer membrane can be controlled by controlled doping of sorbitol within the polymer blends. The PVA–PAA–sorbitol membranes were found to exhibit excellent thermal properties and were stable for a wide temperature range (398–563K), which creates a possibility of using them as suitable polymers for device applications. © 2012 Wiley Periodicals, Inc.

“…PVA is typically mixed with natural polymers to produce biodegradable blends because of its water solubility and thin film forming characteristics. PVA hydrogels are often utilized for biomedical applications because of their biocompatibility, superior adhesion, and blending characteristics . Nevertheless, PVA is a proton conducting material with low conductivity, hence, its electrical conductivity should be enhanced in order to be utilized for device applications including bioimplantable devices .…”

“…In previous investigations, the influences of blending PVA with different ratios of plasticizers on electrical, structural, and mechanical properties of the membranes were examined. The studies demonstrated that the addition of plasticizers to PVA enabled the control of its electrical conductivity and decreased the interaction among the macromolecules that increased the flexibility of its membranes.…”

Polymer membranes of ferrites nanoparticles, glycerol, and poly(vinyl alcohol) (PVA) were fabricated using a solution casting method. Spinel ferrites nanoparticles, CuFe2O4 or ZnFe2O4, and glycerol were used as dopants to control the membranes' electrical conductivity. The morphology, composition, and interaction between PVA and the dopants were investigated byscanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), differentialscanning calorimeter (DSC), and thermal gravimetric analysis (TGA). Electrical characterization of the membranes was conducted by impedance spectroscopy using frequencies between 1 and 106 Hz and variable temperatures. The results revealed a negative temperature coefficient of the resistance of the membranes. Additionally, membranes with ZnFe2O4 nanoparticles exhibit higher electrical impedance than those with CuFe2O4 nanoparticles. Therefore, electrical conductivity could be controlled using a suitable dopant's composition and concentration. The membranes presented in this study exhibit semiconducting properties, thus, they have potentials to be utilized in multiple applications including the flexible organic‐based device. © 2019 Wiley Periodicals, Inc.

“…This mixture was subjected to vigorous mixing to ensure a homogenous texture. Membranes of PVA-PAA-sorbitol were obtained using the solution casting technique (Mohsin, Hossin, and Haik 2011;Ayesh et al 2012). Herein, 20 ml of the mixture was casted onto a PTFE plate to form a thin film and left inside an oven set to 60°C and left overnight.…”

An experimental investigation of an integrated piezo-electric based energy harvester and an organic energy storage device is performed. The energy is harvested from a vibrating composite unimorph beam. The storage device is made out of an organic semiconductor material and storage elements from synthesized nanoparticles. The semiconducting polymer is obtained by blending poly (vinyl alcohol) and poly (acrylic acid) in crystal state polymers with sorbitol acting as the plasticizer. Zinc-Oxide nanoparticles with a diameter size between 50 and 70 nm are used as charge storage elements. A piezoelectric energy generation element made out of macro-fiber composite is used to harvest the energy from the vibrating beam. The harvested energy is stored in the organic capacitor. The performance of the organic device is evaluated through its comparison with commercial capacitors. The results show that the voltage produced was high enough to store the harvested energy in the organic capacitor. The charge and energy levels of the organic capacitor are reported.
