| Research Abstract |
The conical graphitic whisker(CGW) is spindle-shaped carbon consisted of highly ordered turbostratic carbon with helicon-conically distorted stacked hexagonal carbon layers which is produced by vapor phase carbonization with a SiC crystal serving as a seed. CGW could be derived from pyrolysis gas of wood and grown inside the wood cavity. In this study CGW was intercalated with H2SO4 and expanded, without separating from the wood cavity functioning as a scaffold. This indicated that intercalation occurred by supply of electric charge via the cell wall char which enveloped the CGW s. This study suggested the new possibility of inventing functional materials by using cell structure of wood.
