A composite film of Na+-form Nafion and diendoacetylated poly(osyethylene) (Mw = 400) (POE400e) was cast from a dimethylformamide solution at 120 °C. The ionic conductivity of this thin film was measured. The resulting film showed good flexibility, transparency, and no leakage of POE400E up to the POE incorporation of 55 wt %. At this composition, sodium ionic conductivity was 1.0 ✕ 10‒6 S cm‒1, which is relatively high as a single-ion conductor because of the high dissociation of the sodium perfluorosulfonate groups. The ionic conductivity increases with POE incorporation. This can be explained from a decrease in the glass transition temperature (Tg) of POE regions and the connection of ion clusters swollen by POE.
