Polyacrylonitrile (PAN) fibres, also known as acrylic fibres, are fibres spun from copolymers of acrylonitrile with other secondary and tertiary monomers. In addition, PAN fibres are also an important raw material for the formation of carbon fibres.PAN fibres, especially PAN-based nanofibres, are also frequently used in chemical studies for various applications. For example, Qian Yang et al. modified PNA fibres with polydopamine and silver nanoparticles in order to develop functionalized PNA fibres with excellent adsorption properties and long-lasting antimicrobial activity. In this work, the functionalized PAN fibres could maintain more than 90% antimicrobial rate after five washing cycles and could be used for the removal of various metal ions.
