The Influence of AC Perturbations on EIS Measurement of Copper/LDPE Composite with High Resistance

Abstract:

Copper/LDPE composites are novel materials for intrauterine devices and they are the dispersion-type composites with high resistances. When the electrochemical impedance spectroscopy was used to evaluate the properties of materials with high resistances, in order to reduce the fluctuations in the measured data, the AC perturbation should be optimized. In this paper, the effects of the AC perturbations on the electrochemical impedance spectroscopy of copper/LDPE were discussed and the optimal AC perturbation was confirmed. The results have shown that the optimal perturbation of the electrochemical impedance spectroscopy of copper/LDPE composite, in the earlier period was 50mV, after achieving the saturation point the perturbation would change to 5mV.
