Document Type and Number:
Japanese Patent JP4004502
Kind Code:
B2
Abstract:
The present invention discloses ultra-fine fibrous carbon and preparation of the same. Specifically, the present ultra-fine fibrous carbon is characterized by the graphite-like structure with the sp2 hybrid carbon content of more than 95% per total content; the (002) plane interlayer spacing (d002, d-spacing of C(002) profiles determined by X-ray diffraction method) of 0.3370˜0.3700 nm; the (002) plane stacking of more than 4 layers, namely the stacking height (Lc002) of more than 1.5 nm; fibrous carbon length per fibrous carbon width or diameter (aspect ratio) of more than 20; the average diameter of 5˜50 nm.
