The electric energy stored in PEDOT:PSS capacitors integrated on textile substrate

Abstract

Purpose The purpose of this paper is to develop a capacitor fully integrated into a wearable textile fabric for the application on smart clothing. Design/methodology/approach A small capacitor with stainless steel yarns as the electrodes and poly-(3,4–ethylenedioxythiophene): polystryrene sulphonate (PEDOT:PSS) as the dielectric material has been made, integrated into a textile fabric. The electric performance of the capacitor was analyzed and compared with other kinds of electric capacitors. Findings The fabricated small, PEDOT:PSS capacitor could finally power a calculator for 37 s with the energy stored in it. Originality/value This finding is of an important significance for a further development on the capacitor with a better performance.

Enhancing the Conductivity of the Poly(3,4‐ethylenedioxythiophene)‐Poly(styrenesulfonate) Coating and Its Effect on the Performance of Yarn Actuators

“…Poly(3,4‐ethylenedioxythiophene)‐poly(styrenesulfonate) (PEDOT:PSS) is another well‐studied CP due to its structural stability, processability, and high electrical conductivity along with optical transparency . Applications that have been proposed include printed electronics, charge storage devices, solar cells, and textile electronic devices such as wires to connect electronic elements or fabric‐based thermoelectric modules . The use of polar organic solvents such as ethylene glycol (EG), methanol, and dimethylsulfoxide (DMSO) has been shown to increase the conductivity of PEDOT:PSS thin films .…”

Charge-Discharge Characteristics of Textile Energy Storage Devices Having Different PEDOT:PSS Ratios and Conductive Yarns Configuration

“…It is also important to mention that our PEDOT:PSS-based device is a non-linear component, that is, the stored charge is not proportional to the applied voltage, so the capacitance value is not defined. However, it is possible to define an “equivalent” capacitance by the following Equations (5) and (6), assuming for the device charged at 3 V, as detailed in our previous report [40]. 12CeqV02=Eel=0.8101 mJ=0.22 µWh…”

“…The value of Eel was known to be 0.8101 mJ = 0.22 µWh by the calculation described in the paper [40], and therefore, the value of the equivalent capacitance can be calculated as follow:Ceq=2EelV02=180 µF…”

A simple strategy for the construction of bi-supported triazine-based covalent organic frameworks as high-performance capacitive materials

“…In addition, both carbon nanotubes and PEDOT have the advantages of good electrical conductivity, good stability, and controllable morphology, so they can be used as excellent substrate materials for capacitors. [35][36][37] However, there are few reports on the rational incorporation of two conductive substrates into the skeletons of COFs for supercapacitors.…”
