New Electrolytes Findings from Spanish National Research Council (CSIC) Described (Surface modification of sepiolite nanofibers with PEG based compounds to prepare polymer electrolytes)

By a News Reporter-Staff News Editor at Science Letter -- New research on Electrolytes is the subject of a report. According to news originating from Madrid, Spain, by NewsRx correspondents, research stated, "The controlled surface modification of the fibrous clay mineral, sepiolite (Sep), with poly(ethylene glycol) (PEG) and Vitamin E tocopherol polyethylene glycol succinate (TPGS) is presented in this work. Sep, which has a rich surface reactivity because of the presence of silanol groups on its surface, is employed as nanofiller in clay polymer nanocomposites (CPN)."

Our news journalists obtained a quote from the research from Spanish National Research Council (CSIC), "It organizes itself into bundles of nanofibers which are difficult to separate from one another unless aqueous gels are prepared under very specific conditions. In the form of an aqueous gel, however, separation of the nanofibers and chemical modification of their surface can be easily done. Sets of very different organosepiolites (OSep) can be obtained in this way. In this work the resulting OSep are characterized in terms of mass incorporation and yields of reaction, specific surface, surface texture, surface water content and thermal stability. As the final purpose of these OSep is the mechanical reinforcement of poly(ethylene oxide) (PEO) based electrolytes highly loaded with ethylene carbonate (EC), blends with PEG or PEO and lithium triflate, with or without EC are prepared and the properties of the final materials are found to be strongly dependent on the type of OSep employed."

According to the news editors, the research concluded: "In particular, examples on the fillers dispersion in the PEO nanocomposites and on their stability in dispersion of PEG/EC blends are described."
