Thermal Properties of Composite Polymer Electrolytes Poly(Ethylene Oxide)/Sodium Trifluoroacetate/Aluminum Oxide (PEO)(10)CF(3)COONa + x wt.% Al(2)O(3)

Polymeric membranes of poly(ethylene oxide) (PEO) and sodium trifluoroacetate (PEO:CF(3)COONa) combined with different concentrations of aluminum oxide (Al(2)O(3)) particles were analyzed by impedance spectroscopy, differential scanning calorimetry (DSC) and thermogravimetry (TGA). DSC results show...

Sumario:Polymeric membranes of poly(ethylene oxide) (PEO) and sodium trifluoroacetate (PEO:CF(3)COONa) combined with different concentrations of aluminum oxide (Al(2)O(3)) particles were analyzed by impedance spectroscopy, differential scanning calorimetry (DSC) and thermogravimetry (TGA). DSC results show changes in the crystalline fraction of PEO when the concentration of Al(2)O(3) is increased. TGA analysis showed thermal stability up to 430 K showing small changes with the addition of alumina particles. The decrease in crystalline fraction for membranes with low Al(2)O(3) concentration is associated with the increase in conductivity of (PEO)(10)CF(3)COONa + x wt.% Al(2)O(3) composites.
