“…Together with various molar weight PEOs it creates good model polymer electrolyte of high conductivity for investigating the additions effect. PEO-LiCF 3 SO 3 has been widely measured using various methods [24,25] and different values of conductivity, diffusion coefficient and transference number have been reported.…”

“…Further, in a number of cases, lowering of conductivity has been observed upon the addition of NPs. [320][321][322][323][324] While some atomistic simulations have examined the mechanism of ion transport in PNCs and pointed the importance of features such as polymer segmental motion, NP interaction with ions and the polymer segments, and changes in polymer conformations induced by nanoparticles, a number of important features are still unaccounted. [325][326][327][328][329][330][331][332][333] Specifically, due to the detailed and atomistic nature of such simulations, the influence of filler structure and its impact on ionic conductivity has still not been clarified.…”

This topical review discusses the theoretical progress made in the field of polymer nanocomposites, i.e., hybrid materials created by mixing (typically inorganic) nanoparticles (NPs) with organic polymers. It primarily focuses on the outstanding issues in this field and is structured around five separate topics: (i) the synthesis of functionalized nanoparticles; (ii) their phase behavior when mixed with a homopolymer matrix and their assembly into well-defined superstructures; (iii) the role of processing on the structures realized by these hybrid materials and the role of the mobilities of the different constituents; (iv) the role of external fields (electric, magnetic) in the active assembly of the NPs; and (v) the engineering properties that result and the factors that control them. While the most is known about topic (ii), we believe that significant progress needs to be made in the other four topics before the practical promise offered by these materials can be realized. This review delineates the most pressing issues on these topics and poses specific questions that we believe need to be addressed in the immediate future. Published by AIP Publishing. [http://dx

“…Ionic transport number measurement is one of the vital characterization techniques in the optimization of a polymer electrolyte for battery application and an appreciably high transference number value would indicate a rapid charge-discharge characteristic which is widely desirable [23][24][25]. Ionic conductivity in the case of an electrolyte is essentially the sum of the contributions of both cations and anions under the application of an external electric field.…”

This paper reports on preparation and characterization of thin films of a new zinc ion conducting blended polymer electrolyte system containing polyethylene oxide [PEO] and polypropylene glycol [PPG] complexed with zinc triflate [Zn(CF 3 SO 3 ) 2 ] salt. The room temperature ionic conductivity (σ 298K ) data of such PEO-PPG polymer blends prepared by solution casting technique were found to be of the order of 10 −5 S cm −1 , whereas the optimized composition containing 90:10 wt% ratio of PEO and PPG possessed an appreciably high ionic conductivity of 7.5 × 10 −5 S cm −1 . Subsequently, six different weight percentages of zinc triflate viz., 2.5, 5, 7.5, 10, 12.5 and 15, respectively, were added into the above polymer blend and resulting polymer-salt complexes were characterized by means of various analytical tools. Interestingly, the best conducting specimen namely 87.5 wt% (PEO:PPG)-12.5 wt% Zn(CF 3 SO 3 ) 2 exhibited an enhanced room temperature ionic conductivity of 6.9 × 10 −4 S cm −1 with an activation energy of 0.6 eV for ionic conduction. The present XRD results have indicated the occurrence of characteristic PEO peaks and effects of salt concentration on the observed intensity of these diffraction peaks. Appropriate values of degree of crystallinity for different samples were derived from both XRD and DSC analyses, while an examination of surface morphology of the blended polymer electrolyte system has revealed the formation of homogenous spherulites involving a rough surface and relevant zinc ionic transport number was found to be 0.59 at room temperature for the best conducting polymer electrolyte system thus developed.
