“…The activation energy as tabulated in Table 1 decreases as conductivity of sample increases implying that the ions in highly conducting samples require lower energy for migration. This is possibly due to the smaller size of nanofiller and plasticizer molecules compared to polymer host molecule and which can very easily penetrate into the polymer matrix resulting to an interaction between filler, plasticizer, and polymer chain molecules [18]. This, in all probability, may reduce the cohesive forces operating between the polymer chains, thereby, resulting to an increase in chain segmental motion.…”

We report a new kind of polyethylene oxide, PEO-LiCF 3 SO 3 -based composite polymer electrolyte, containing active copper oxide (CuO) nanoparticles with dibutyl phthalate (DBP) prepared by solution-cast technique. The incorporation of 10 wt.% DBP and 5 wt.% CuO to the salted polymer showed a significant conductivity enhancement with maximum conductivity 2.62 × 10 −4 Scm −1 at room temperature. This could be attributed to the increasing of amorphous phase content and structural changes in the polymer electrolyte. Arrhenius plot suggest that temperature-dependent conductivity is a thermally activated process.

“…Most of the reports are related to either the effect of filler or plasticizer on the properties of polymersalt complex. To the best of our knowledge, only a very few reports are available in the literature which discuss the combined effect of filler and plasticizer on polymer electrolytes [17][18][19][20][21]. In this paper, we report a systematic investigation on the effect of plasticizer on the microstructural/structural and electrical properties of the PNCEs.…”

The solid polymer electrolyte films based on polyethylene oxide, NaClO 4 with dodecyl amine modified montmorillonite as filler, and polyethylene glycol as plasticizer were prepared by a tape casting method. The effect of plasticization on structural, microstructural, and electrical properties of the materials has been investigated. A systematic change in the structural and microstructural properties of plasticized polymer nanocomposite electrolytes (PPNCEs) on addition of plasticizer was observed in our X-ray diffraction pattern and scanning electron microscopy micrographs. Complex impedance analysis technique was used to calculate the electrical properties of the nanocomposites. Addition of plasticizer has resulted in the lowering of the glass transition temperature, effective dissociation of the salt, and enhancement in the electrical conductivity. The maximum value of conductivity obtained was ∼4.4×10 −6 S cm −1 (on addition of ∼20% plasticizer), which is an order of magnitude higher than that of pure polymer nanocomposite electrolyte films (2.82×10 −7 S cm −1 ). The enhancement in conductivity on plasticization was well correlated with the change in other physical properties.

“…The results are in accordance with the bulk resistance values which showed bulk resistance in the order of cG1<cG3<cG5. As a matter of fact, the conductivity of the formulations is inversely proportional to the bulk resistance (50). The d.c. conductivity of the formulations was calculated by the linear extrapolation of the high frequency a.c. conductivity to d.c. frequency.…”

Abstract. The present study discusses about the preparation and characterization (thermal, mechanical, and electrical) of the genipin-crosslinked gelatin emulgels. Emulgels have gained importance in recent years due to their improved stability than emulsions and ability to control the drug release. Mustard oil was used as the representative oil. A decrease in the enthalpy and entropy of the formulations was observed with the increase in the oil fraction. The mechanical studies suggested formation of softer emulgels as the oil fraction was increased. As the proportion of the oil fraction was increased in the emulgels, there was a corresponding increase in the impedance. The drug release properties from the emulgels were also studied. Ciprofloxacin was used as the model antimicrobial drug. The drug release was higher from the emulgels whose electrical conductivity was higher.
