Polyaniline is a type of conducting polymer, which means it can conduct electricity while still being flexible and lightweight. It is made from aniline, a simple organic compound, and is known for its unique properties, such as its ability to change color when exposed to different pH levels. This makes polyaniline useful in various applications, including sensors and electronic devices. One of the exciting features of polyaniline is its potential in the field of energy storage. It can be used in batteries and supercapacitors, helping to improve their efficiency and lifespan. Researchers are continually exploring new ways to utilize polyaniline in smart materials and wearable technology, making it a promising area of study in modern science.
