Jm. Ma et al., SYNTHESIS, STRUCTURE AND CONDUCTIVITY CHA RACTERISTICS OF SEGMENTED COPOLYMER ELECTROLYTE WITH SULFONATE, Gaodeng xuexiao huaxue xuebao, 16(10), 1995, pp. 1645-1649
The transesterification and polycondensition of hydroxy terminated pol
yethylene oxide and ethylene glycol with dimethyl terephthalate and so
dium dimethyl isophthalate sulfonate lead to the formation of ethylene
oxide-(ethylene terephthalate-CO-sodium ethylene isophthalate sulfona
te) segmented copolymer (EOTM-SO3Na). This segmented copolymer is a ne
w single cationic conductor, The chain and aggregate structure of EOTM
-SO3Na segmented copolymers were characterized by H-1 NMR , WAXD and D
SC methods, The ion mobility measured by polar inversion method was ap
proach to 1, The room temperature conductivity of EOTM-SO,Na cationic
conductor can get 2, 3X10(-6) S . cm(-1). The temperature dependence o
f the cationic conductivity for EOTM-SO3Na system can be described by
VTF equation.
