| 總結: | In this project, the PEO-based solid polymer electrolyte was successfully prepared by
solution casting method. Polyethylene oxide (PEO) used as host polymer while
potassium iodide (KI) as salt. The effect of KI concentration on the ionic conductivity
of the electrolyte was investigated. The interaction between salt and polymer in
sample PEO/KI/I2 was studied by Fourier transform infrared spectroscopy (FTIR)
while the ionic conductivity was measured using electrochemical impedance
spectroscopy (EIS). The ionic conductivity was found to increase with the increasing
of the amount of KI. However, a maximum ionic conductivity value 3.04 x 10-5 Scm-I
was obtained from sample PEO-KI/I2 with mass of ratio 6:3:1. These results revealed
that the KI increase the ionic conductivity of the polymer electrolytes due to the
change in the polymer chains and crystallization phase |
