Description

technical field [0001] The invention relates to a composite carbon material, in particular to a preparation method of a heterogeneous nanoscale composite carbon material. Background technique [0002] Carbon is one of the most widely distributed elements in nature, and it has a variety of electronic orbital characteristics (SP, SP 2 , SP 3 Hybridization), so allotropes with very different structures and properties can be formed, such as zero-dimensional carbon black and fullerene, one-dimensional carbon nanotube (CNT) and carbon nanofiber (CNF), two-dimensional graphite These carbon materials have unique and excellent mechanical, electrical and thermal properties. These properties make this kind of nanomaterials occupy an irreplaceable position and role, and make them ideal materials for various reinforcing fillers and electrical and thermal conductivity. , so the preparation and application of nanocomposites has increasingly become the focus of research. [0003] Graphen...
