Polyaniline, also known as PANI, is a polymer in the that is becoming more significant for academics in the field of nanotechnology due to the potential uses it has in sensor technologies, optoelectronics, and photonics. PANI can be rapidly doped by a broad range of acids and dopants due to the ease with which it may be manufactured and its exceptional resilience in the natural environment. In this article, we will discuss the redox and antioxidant properties of several substances, as well as their resistance to corrosion and electricity, sensing capabilities, and magnetic properties. In order to do this, we looked at the properties of the conducting polymer PANI and have discussed them briefly. It has been shown that the circumstances under which PANI is polymerized do not need to be changed in any way for it to be useful in a wide variety of scientific and technical applications. Matrix synthesis, which is often performed using PANI, is the method of choice for the creation of composite materials that are both electroactive and conductive. This article provides a concise survey of the uses of PANI and related composites in the field of polymer electronics.
