Latest Patents

Zhiheng Sun 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 to create a mixture that is extruded and pelletized, leading to the production of nascent fibers. These fibers undergo stretching and annealing to form a PAN-based carbon fiber precursor. The precursor is then subjected to ultraviolet irradiation, followed by pre-oxidation and carbonization to yield the final PAN-based carbon fibers. This innovative approach is crucial for advancing carbon fiber technology.
