| Outline of Final Research Achievements |
Cone-shaped graphitic whiskers (CGW) are easily produced by carbonization of woody plants, via heat treatment at >2000°C together with SiC, which works as nuclei for a stable growth of CGWs. Our crystallographic study with transmission microscopy characterized CGWs as super-helical cone stack of graphene. The intercalation behavior and contract-expand mobile behavior of CGW were revealed and the mechanisms were clarified. The density gradient centrifugation method was used to successfully separate CGWs from impurities. This can be further applied for sample preparations for measurements of their unrevealed unique properties. Plant-cell-mimic "microreactor" was synthesized with biopolymer and the generation mechanism of CGWs in plant cell cavity was discussed.
