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, including textiles, carbon fibers, and coatings. In the textile industry, polyacrylonitrile is often used to produce acrylic fibers, which are lightweight and warm, resembling wool. Additionally, PAN serves as a precursor for creating carbon fibers, which are essential in aerospace, automotive, and sporting goods due to their exceptional strength-to-weight ratio.
