✦ Synopsis

Benzene-derived carbon fiber (BDF) and mesophase-pitch carbon fiber (MPPCF) were intercalated with H2S04 by the electrochemical method and the stage characteristics observed on the potential curve. X-ray diffraction and Raman scattering studies indicate that stage I, 2, 3, and 4 H$O,-graphite fiber intercalation compounds (GFICs) have been obtained. The intercalation is homogeneous along the fiber axis for MPPCF, but is not for BDF. The stability of H2S04-GFICs is poorer than that of HzS04graphite intercalation compounds (GICs).

By means of cyclic voltammetry, a study of the redox reactions has been made on stage 1 sulfuric acid-graphite intercalation compound (H,SO,-GIC) prepared by anodic oxidation of graphite in sulfuric acid electrolyte. It was found that further oxidation of the stage 1 GIC gives rise to the reversible

Raman spectra of graphite fibers intercalated with K, Rb and Cs are reported. X-Ray diffraction is used to characterize the fibers with respect to staging. We report results mainly for GY70, a highly graphitic commercially available fiber, which is polyacrylonitrile (PAN) based, and some results on
