What is the heating principle of carbon nanotube electric heating film?

Mondo Science Updated on 2024-01-29

Plastic high-tech materials Carbon nanotube electric heating film is a technology that uses the characteristics of carbon nanotube materials to generate heat. The heating principle is mainly based on the resistance heating effect of carbon nanotubes.

Carbon nanotubes have excellent electrical and thermal conductivity, and when an electric current is applied through the carbon nanotubes, the current creates resistance within the carbon nanotubes, causing the carbon nanotubes to heat up. This is because the diameter of carbon nanotubes is very small, and the movement of electrons inside them is scattered and hindered by the surface of carbon nanotubes, resulting in a large resistance. By adjusting the amount of current, the heating temperature of carbon nanotubes can be controlled.

Carbon nanotube heating films typically consist of multiple layers of carbon nanotube films that are integrated into the substrate material. When an electric current is applied, the carbon nanotubes in the carbon nanotube film heat up and transfer heat to the surrounding environment, realizing the heating effect of the electric heating film.

Carbon nanotube electric heating film has the advantages of fast response, uniform heating and low energy consumption, and has a wide range of application potential in many fields, such as electric heaters and thermal induction materials.
