Plasticizer effects in polyether electrolytes studied by positron annihilation lifetime spectroscopy
journal contribution

Despite their very different behaviour as observed by NMR and conductivity measurement, the PALS sensitive free volume of the samples changes in a similar way on addition of the two plasticizers. It is concluded that the effect of these plasticizers on conductivity is determined more by their effect on ion-polymer and ion-ion interactions than by their effect on the PALS free volume.
