What is Supercapacitors

Polypyrrole, polythiophene, and PANI are inherently conducting polymers (ICPs), which show electrical properties just like metals and semiconductors. Aniline has low cost, so it makes PANI the least expensive and thermally stable from all ICPs. PANI is conducting in nature, but due to its less solubility and melting processability, it has not much attention for commercial purposes. PANI might be used for commercial purposes following by some additional improvements. It can be synthesized by electrochemical and chemical oxidative polymerization. PANI thin films can be used in the detection of gases as gas sensors, chemical and biological sensors, optical pH sensors, etc. These films can also be used in supercapacitors, electrochromic devices, solar cells, dye-sensitized solar cells, rechargeable batteries, electrochemical filter, protection of metal surface from corrosion, etc. PANI thin films can also be used in biological applications such as antimicrobial properties, and the various researchers across the globe have the most widely studied tissue engineering applications.
