Polyacrylonitrile (PAN) is a synthetic polymer made from the polymerization of acrylonitrile monomers. It is known for its high strength, thermal stability, and resistance to chemicals, making it useful in various applications. PAN is commonly used in the production of fibers, such as those found in clothing and textiles, as well as in the manufacturing of carbon fibers, which are essential in aerospace and automotive industries. In addition to its use in textiles, Polyacrylonitrile serves as a precursor for carbon fiber production, where it is heated to high temperatures to create lightweight and strong materials. Its properties also make it suitable for applications in filtration, coatings, and as a component in certain types of batteries.
