Latest Patents

Xujian Yang holds a patent for a method of preparing PAN-based carbon fibers. This method involves several key steps: first, acrylonitrile, a second monomer, and an unsaturated UV-sensitive cross-linking agent are mixed, followed by the addition of an initiator to obtain a meltable PAN-based copolymer. Next, this copolymer is combined with a flow modifier, extruded, and pelletized to create nascent fibers. These fibers undergo stretching and annealing to form a precursor, which is then subjected to ultraviolet irradiation. Finally, the precursor is pre-oxidized and carbonized to produce the final PAN-based carbon fibers. This innovative approach is crucial for advancing carbon fiber technology.
