| Abstract Scope |
Preparation of coal liquefaction residue/polyacrylonitrile (PAN) composite carbon nanofibers using extract from coal liquefaction residue (CLRE) and PAN. The structure and morphology of composite carbon nanofibers was analyzed by SEM and FT-IR. Due to the analysis on the properties of composite carbon fibers with different additive amounts, 10% of CLRE in the solution was considered as the optimized additive amounts, as integrated fiber morphology and homogeneous structure. With the increase of the additive amount of CLRE, the spinnability decreases, and reticular and foam-like structures were formed. However, the diameter of the obtained CLRE-PAN composite carbon fibers was smaller. Therefore, the optimization additive amount is 30%, carbonization temperature is 400℃, and fiber diameter ranges from 210 nm to 450 nm. The composite carbon nanofiber has good reversibility in the process of charge and discharge. |
