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 and carbon fiber production. PAN fibers are lightweight and have excellent dyeability, which enhances their use in clothing and industrial materials. In addition to textiles, PAN is a key precursor for producing carbon fibers, which are used in aerospace, automotive, and sporting goods industries due to their high tensile strength and low weight. The versatility of PAN contributes to advancements in materials science and engineering.
