Description

technical field

[0001] The invention relates to a preparation method of a carbon nanotube film, in particular to an electrophoretic deposition preparation method, and belongs to the technical field of nanometer materials. Background technique

[0002] Carbon nanotubes are currently an ideal one-dimensional nanomaterial prepared artificially. Due to their unique composition and structure, carbon nanotubes exhibit many unique physical properties, and are widely used in sensors, flat panel displays, supercapacitors, composite materials, etc. a wide range of applications. Among them, the prospect of the application of the macroscopic film structure composed of carbon nanotubes according to certain rules is more exciting.

[0003] At present, the preparation methods of carbon nanotube films mainly include direct growth method and post-processing method.

[0004] The direct growth method is to use arc discharge, laser ablation, chemical vapor deposition and other preparation met...
