Abstract:
The work focused on studying the eff ect of charging voltage level and the absence of electrode between
the measured electrodes on the charge storage profi le. The device was applied on a three layered of 5 x
5 cm laminated textile fabric with hydrophobic surface. Stainless steel fi lament yarns were used as electrodes. As electrolyte, seven layers of the electro-active polymer PEDOT:PSS dispersion was consecutively
drop-coated and dried under the temperature of 90–100 °C. During the course of the experiments, the devices were charged and discharged and their response or voltage decay was recorded. The results showed
that the higher the charging voltage, the higher the amount of charges stored. The increase in the output
voltage was not proportional to the input voltage which means that the device did not behave as either a
pure capacitor or a pure battery. The ions movement was confi rmed to be involved in the charge-discharge
mechanism of the device.
