Abstract

The rapidly growing interest in energy storage systems has tempted researchers to develop new materials that can store a large amount of energy. conducting polymers that present a well-known interest in different research areas due to their high potential applications in displays and molecular devices, smart windows, energy storage systems, and as corrosion protective layers. It can replace metals and semiconductors, because of their conductivity, low density, and easy synthesis. Polyaniline (PANI) is one of the most commonly studied conducting polymers with a broad application potential. Carbon nanotubes have become one of the most materials used as supporting material for PANI and it can be coating PANI on its surface as shell Nanostructure composites to improve the polyaniline cycling stability and the properties of PANI/MWCNT composites are intermediate between pure PANI and MWCNT. Therefore, the electrochemical properties of these composites are enhanced compared to the two individual components.This work is related to explore a new method to improve the electrochemical behavior of the electrodes which can be used in energy storage device applications and improving their performance. The work is divided into two main parts related to the preparation of polyaniline and polyaniline/multi-walled-carbon Nanotubes on different stainless steel substrates.
First, a simple, inexpensive technique used for the preparation of the polyaniline powder chemically and preparation of the PANI and PANI/MWCNT composite as an active material deposited on solid stainless steel flat sheet and mesh sheet by using electrophoresis deposition technique. The usage of mesh flexible sheet is favorable due to its larger surface area than the surface area of the solid sheet, and the flexibility of the mesh sheet increases the variety of its applications. Second, the produced electrodes were fully characterized regarding structure, morphology, and electrochemical performance. The specific capacitance of the electrodes was 233.7 F g-1, 295.5 F g-1, 269 F g-1, and 363 F g-1 for the PANI, and PANI/MWCNT electrodes deposited on the St. Steel flat sheet and screen sheet respectively at the scan rate of 10.0 mV s-1.Finally, it could be concluded that we developed a novel flexible mesh electrode for several applications in energy storage devices such as supercapacitors.
