Structure, Interaction and Thermal Study in Electrolyte of Polyethylene Oxide/Silica/Ammonium Thiocynate Nanocomposites

摘要

Composite polymer electrolyte consisting of polymer (polyethylene oxide, PEO) and nanosized ceramic filler with different concentrations of salt have been synthesized and characterized. X-ray diffraction analysis shows that polymer salt complex has been intercalated into the naometric silicate layers. IR spectra reveal that the polymer structure in the ceramic interlayer is similar to that of polymer salt complexes and there is a strong interaction between PEO:SiO2 and polymer-salt complexes.
