Description

Technical Field

[0001] This utility model relates to the field of electric field orientation technology of carbon nanotubes, and in particular to a carbon nanotube electric field orientation device. Background Technology

[0002] Carbon nanotubes are one-dimensional quantum materials composed of carbon atoms. They typically consist of several to dozens of layers of coaxial cylindrical tubes arranged in a hexagonal pattern. Classified as single-walled and multi-walled carbon nanotubes, they possess excellent properties such as high strength and high conductivity, and have broad application prospects in various fields. In related applications, electric field orientation devices can be used to align carbon nanotubes in an orderly manner using electric fields, improving their electron transport efficiency in electronic devices; they can also be used to orient carbon nanotubes in composite materials, enhancing their directional properties; they can facilitate their bonding with other materials, making them easier to process and shape; and they can meet the precise control requirements of high-end fields such as nanoelectronics.

[0003] Currently, most common electric field orientation devices involve placing a petri dish containing carbon nanotube solution directly between two electrode plates.
