Abstract:

This experiment adopts electrospinning to prepare the PAN/PMMA gel polymer electrolyte membrane.The conductivity under different temperature was tested by AC impedance.The impact of temperature on the ion transport properties of composite gel polymer electrolyte membrane was explored.The prepared membrane was also compared with PAN/PMMA flat synovial membrane made by solvent casting method.The conductive kinetics of the two different forms of membranes was analyzed.The relationship between their conductive mechanism and microstructure was explored.The results showed that the conductive mechanism of the two kinds of membranes conforms to the Arrhenius formula, with the membrane made by electrostatic spinning having lower ion conductive activation energy.

Key words: Electrostatic spinning, AC impedance, Activation energy, Ionic conductivity
