“…In addition, among various electrode materials, polyaniline (PANI) has been reported as a promising candidate because of its low cost, high theoretical capacitance, easy synthesis, and good environmental stability . It has found many interesting applications in fuel cells, corrosion protection, sensors, supercapacitors, and electromagnetic shielding . In order to improve the performances of PANI, various morphologies such as nanotubes, nanosheets, nanofibers, and nanospheres were constructed to enlarge the active surface area for electrochemical reaction .…”

Fiber-shaped supercapacitors have drawn much attention for their great potential application in future portable and wearable electronics because of their outstanding flexibility, tiny volume, and good deformability. In this work, commercial poly(ethylene terephthalate) (PET) thread was successfully converted into an electrically conductive and electrochemically active thread by introducing copper sulfide (CuS) and polyaniline (PANI) via simple chemical bath deposition and electrochemical deposition. The obtained PANI/CuS/PET electrode combined all the advantages of PET, CuS, and PANI, showing an excellent physical and electrochemical performance. The fiber-shaped supercapacitor exhibits a high specific capacitance of 29 mF cm −2 (116 mF cm −2 for a single electrode) and good cycling stability with 93.1% retention after 1000 cycles. With the simple preparation method and low-cost raw materials, this strategy provides a reference for the fabrication of portable/wearable energy storage devices.

“…In the present work thermal stability of emeraldine salt is evaluated in more detail. The emeraldine salt was synthesized by another very fruitful emulsion polymerization method [25] using dodecylbenzenesulfonic acid (DBSA) as surfactant and dopant. In this pathway, sulfuric acid (H 2 SO 4 ) was used as codopant for the first time.…”

A comprehensive study of thermally treated polyaniline in its emeraldine salt form is presented here. It offers an understanding of the thermal stability of the polymer. Emeraldine salt was prepared by a novel emulsion polymerization pathway using dodecylbenzene sulfonic acid and sulfuric acid together as dopants. The effect of temperature and heating rate on the degradation of this emeraldine salt was studied via thermogravimetric analysis. The thermally analyzed sample was collected at various temperatures, that is, 250, 490, 500, and 1000 ∘ C. The gradual changes in the structure of the emeraldine salt were followed through cyclic voltammetry, Fourier transform infrared spectroscopy, and ultraviolet-visible spectroscopy. Results demonstrate that emeraldine salt shows high thermal stability up to 500 ∘ C. This is much higher working temperature for the use of emeraldine salt in higher temperature applications. Further heat treatment seems to induce deprotonation in emeraldine salt. Cyclic voltammetry and ultraviolet-visible spectroscopy revealed that complete deprotonation takes place at 1000 ∘ C where it loses its electrical conductivity. It is interesting to note that after the elimination of the dopants, the basic backbone of emeraldine salt was not destroyed. The results reveal that the dopants employed have a stability effect on the skeleton of emeraldine salt.
