T. Mani et al., THE PHYSICAL CHARACTERISTICS OF PPG PMMA/LICF3SO3 POLYMER ELECTROLYTEBLENDS INCLUDING MORPHOLOGY/, Solid state ionics, 60(1-3), 1993, pp. 113-117
Adhesive and transparent polymer blend electrolytes were synthesized b
y the free radical polymerization of methyl methacrylate (MMA) in poly
(propylene glycol) (PPG) complexed with lithium triflate (LiCF3SO3).
Polymer electrolytes with differing PPG molecular weights, PMMA compos
ition, and O/Li ratios were prepared. The physical characteristics of
the polymer blend electrolytes were found to depend on the PPG molecul
ar weight, salt concentration and PMMA content. SEM studies indicated
the polymer blends to have a phase separated morphology. The salt, LiC
F3SO3, was found to act as an emulsifier in stabilizing the two phase
microstructure of the blends.
