Abstract
Ionic conducitivity and mobility were investigated in poly(propylene oxide) (PPO) networks dissolving the alkali metal thiocyanates, LiSCN, NaSCN, and KSCN. The temperature dependence of ionic conductivity of the PPO complexes, estimated from complex impedance method, obeyed the WLF-type equation with C1=9—15 and C2=35—80. At a reduced temperature of Tg+100 C, the magnitude of conductivity was of the order of 10−6—10−5 Scm−1, following the order of PPO-KSCN>PPO-NaSCN>PPO-LiSCN. Ionic mobility was estimated from an initial slope of the current-time curve with a first d.c. voltage application and from the time of current maximum after reversal of the applied voltage polarity, assuming the clean-up effect of carrier ions to dominate the time dependence of the current. The ionic mobility at Tg+100 C did not greatly depend on the kinds of incorporated salts and was of the order of 10−6—10−5 cm2 V−1 s−1. Somewhat lower ionic mobilities were deduced by the latter method.
