摘要: Carbon materials have particular characteristics due to differences in chemical bond formation. Allotropic forms of carbon that been discovered can be categorized into five types from the standpoint type hybridization valence orbitals: (1) sp 3-hybridization; (2) 2-hybridization; (3) sp-hybridization; (4) mixed (sp 3 + 2); and (5) a valance state characterized by fractional degree m , where 1 < 3, ≠ 2) [1]. Diamond, carbynes, diamond-like carbon, fullerenes correspond groups (1), (3), (4), (5), respectively.
