Description

technical field

[0001] The invention belongs to the technical field of new material preparation, and in particular relates to a heteroatom-doped carbon nanotube-graphene composite and a method for preparing the heteroatom-doped carbon nanotube-graphene composite based on a sheet material. Background technique

[0002] Carbon nanotubes can be regarded as a one-dimensional tubular nanocarbon material formed by curling graphene sheets. The carbon atoms in the ideal carbon nanotube structure are all sp 2 Hybrid bonding method with huge aspect ratio. The structural characteristics of carbon nanotubes determine that they have excellent electromagnetic, mechanical, thermal and other excellent properties. However, in the actual application process, carbon nanotubes are prone to aggregate due to the strong van der Waals force between them, making it difficult to disperse, which seriously hinders the full play of their excellent properties. Graphene is a two-dimensional nano-carbon...
