| Abstract: | A novel carbon fiber pretreatment was proposed. Polyacrylonitrile (PAN)-based carbon fibers were first anodized in H3PO4 electrolyte to achieve an active surface, and then coated with Mo-B catalysts by immersed the carbon fibers in a uniformly
dispersed Mo-B sol. The as-treated carbon fibers were then graphitized at 2 400 °C for 2 h. The structural changes were characterized
by X-ray diffractometry (XRD), Raman spectroscopy, scanning electron microscopy (SEM) and high-resolution transmission electronic
microscopy (HRTEM). The results show that much better graphitization can be achieved in the presence of Mo-B, with an interlayer
spacing (d
002) of 0.335 8 nm and a crystalline size (L
c) of 28 nm. |
