Abstract

The relationship between ionic conduction and matrix glass transition was investigated in selected plasticized and doped poly((ethylene glycol) _n-co-5-sulfoisophthalate lithium) ionomers. Plasticization with a poly(ethylene glycol) oligomer significantly increases the ionic conductivity, despite a decrease in lithium concentration. Doping with LiClO₄ leads to much lower conductivity, despite the increase in Li⁺ content. These observations were reconciled by considering the corresponding change in ionomer glass transition temperature (T_g), and it was found that ionomers with different plasticizer/dopant levels exhibit similar conductivity at constant T - T_g. The fact that T_g plays such a strong role suggests that Li⁺ ion mobility is controlled by segmental motion of PEO.
