The bottleneck in the preparation of polyacrylonitrile-based carbon fiber precursors has been solved and there is huge room for development

Polyacrylonitrile (PAN)-based carbon fiber is a fiber made of acrylonitrile homopolymer or acrylonitrile-based copolymer. It is a new inorganic fibrous material with a carbon mass fraction of more than 90%. It has high strength and high With excellent properties such as modulus, high temperature resistance, and corrosion resistance, it is widely used in aerospace, transportation,…
