Latest Patents

Yonggang Cao holds a patent for the preparation methods of high modulus carbon fiber (HMCF) and its precursor, mesophase pitch (MP). The preparation method involves several key steps, including the separation of components with a molecular weight distribution (MWD) of 400 to 1,000 from heavy oil raw material using size-exclusion chromatography (SEC). The components are then subjected to ion-exchange chromatography (IEC) to obtain modified feedstock oil. This process effectively removes acidic and alkaline components, resulting in high-quality MP with excellent spinnability. The MP can subsequently be used for melt spinning, pre-oxidation, carbonization, and graphitization to produce MP-based HMCF.
