Abstract
Synthesis and electrical conductivities of polymeric blends in the ter nary system PEO-PPG-NaClO4 are reported. The blends change from crysta lline to amorphous with progressive substitution of PPG for PEO in the ternary at a fixed PPG concentration. Highest electrical conductivity of 1.85 x 10(-4) (OMEGA cm)-1 at room temperature is observed for a b lend, PEO-12%PPG-NaClO4 with O/Na=4. This composition is found to be c ompletely amorphous when characterised by X-ray and DSC. The enhanced ionic conduction in these blends has been attributed to the reduced cr ystallinity.
