Polyacrylonitrile is widely used in the production of carbon fibers, which are essential in manufacturing lightweight and high-strength materials for aerospace, automotive, and sports equipment industries. It serves as a precursor for these fibers due to its ability to withstand high temperatures and its excellent mechanical properties. In the textile industry, it is utilized to create synthetic fibers known as acrylic fibers, which are valued for their softness, warmth, and resistance to sunlight and chemicals. These fibers are commonly used in making clothing, upholstery, and carpets. Additionally, polyacrylonitrile is employed in the production of membranes for water purification and gas separation processes. Its durability and chemical resistance make it suitable for filtration applications in various industrial settings. It also finds use in the creation of specialty papers and coatings, where its thermal stability and strength enhance the performance of the final products.
