“…The activation energy obtained using the slope of the plot is 0.16 eV. This value of activation energy is very much in agreement of previous reports (Osman et al, 2012). The low activation energy may be due to completely amorphous nature of the GPE.…”

Solid state redox capacitors have received a tremendous interest in terms of several characteristics such as their fast energy delivery, short charging time, high power density and extended durability. Due to the absence of a liquid electrolyte, they are free from drawbacks of leakage and unsafe. In this study, preparation and characterization of a redox capacitor consisting with two identical polypyrrole (PPy): dodecylbenzenesulfonate (DBS) electrodes and a gel polymer electrolyte (GPE) based on polyvinylidene fluoride (PVdF), ethylene carbonate (EC), propylene carbonate (PC) and sodium thiocyanate (NaSCN) is reported. The GPE having the composition, 0.4 PVdF: 1 EC: 1 PC: 0.075 NaSCN (by weight) showed the maximum conductivity of 2.25× 10 -3 S cm -1 . Redox capacitors were characterized using Cyclic Voltammetry, Electrochemical Impedance Spectroscopy and Galvanostatic Charge Discharge test. They exhibited an energy density about 0.25 W h kg -1 and an average power density of 4 kW kg -1

“…Further increment of salt can lead to create ion aggregates in GPE so that number of free ions which participate for conductivity also decreases. Thus, the conductivity decreases (Osman et al, 2012). The highest conducting sample (PVdF 0.5: EC 1.0: PC 1.0: NaSCN 0.075) was further optimized by changing the concentration of the polymer.…”

“…Since the prototype RMGIC contains both water and THMM, both electronic conductivity and ionic conductivity contribute to the current value 18) . The two conductivity, however, was not evaluated separately in this paper, but the total ability conducting electric current was evaluated qualitatively as "electrical conductivity".…”

Electrical shear bonding strength reduction of resin-modified glass-ionomercement containing ionic-liquid: Concept and validation of a smart dental cement debonding-on-demand

et al. 2018

With improvement of bonding strength of recent dental cement, it is difficult nowadays to remove restorations without excessive force or vibration to tooth, occasionally resulting in damage of dentin, enamel, and dental root. Therefore, "smart" dental cement indicating strong bonding and easy debonding-on-demand simultaneously is required. In this research, resin-modified glass-ionomer-cement containing an ionic-liquid, tris(2-hydroxyethyl)methylammonium methylsulfate was produced, and the shear bonding strength before and after direct current application were evaluated. The prototype cement containing 15 to 20 mass% ionic-liquid indicated simultaneously no significant reduction of shear bonding strength from that of the original cement not containing ionic-liquid, and significant reduction of bonding strength to approximately 20% of that of the original cement after direct current application of more than 2 mmC/mm 2 . The prototype cement in this research demonstrated that the concept of smart dental cement electrically debonding-on-demand is feasible.

“…These Cole-Cole plots could be separated into three components ; the equivalent circuits of the components are shown in Fig. 6b, where Rs is the high-frequency limiting resistance corresponding to the resistance of the gel liquid phase, which consists of water and a small amount of free MA molecules [30]. The distributed circuit elements (DCE) [31], Z1 and Z2, were estimated as summarized in Table 1 ; Z1 is the DCE derived from proton conduction between the IG and HEA networks [32] and Z2 is the DCE derived from proton conduction through the hydrogen bridges among the protonated aluminol groups on the IG surface as well as the carboxylic groups in the MA molecules attached to IG [33], i.e., the hydrogen bridges along the Al(OH)O + H2 bonding motif of IG or outer COOH groups of the MA sheath, respectively.…”
