“…In this study we prepare a polyether/clay nanocomposite electrolyte, using the scCO 2 processing technique, as a novel SPE. The clay used is saponite, which can have greater conductivity than the MMT and also shows good conductivity as a filler for PEO . We study the effect of scCO 2 treatment on the dispersion state of clay, the thermal properties and the conductivities of polyether/saponite composites.…”
