Hereinafter, the application position and function of the member including the carbon nanotubes will be described.

(1) Members containing carbon nanotubes form the appearance of home appliances

The member including the carbon nanotubes may form an external appearance of the home appliance. The carbon nanotubes are light in weight and have excellent electrical resistance. In addition, the carbon nanotubes are about 10 to 100 times stronger than iron, and have excellent ductility and excellent sound absorption performance. Further, due to the excellent electrical resistance of the carbon nanotubes, the surface resistance of the member including the carbon nanotubes becomes larger than that of the member not containing the carbon nanotubes.

In addition, the strength of the home appliance can be improved by the member including the carbon nanotubes. In addition, the noise generated inside the home appliance can be reduced by the member including the carbon nanotubes.

(2) Applied to the part in contact with the air inside home appliances

The member including the carbon nanotubes may form or provide an air flow path inside the home appliance. For example, an air passage such as an air conditioner or a cleaner may be formed.

Therefore, according to the member including the carbon nanotubes, it is possible to prevent the dust inside the home appliance is attached to the member containing the carbon nanotubes. Of course, the carbon nanotube-containing member may further obtain an effect of improving the strength by the properties of the carbon nanotubes.

(3) Applied to heating element and radiator

The member including the carbon nanotubes may be applied to the heating portion of the heating element.

Therefore, when the member including the carbon nanotubes is applied to the heat generating portion or the heat dissipating portion of the heating element, excellent thermal conductivity can be obtained and strength can be improved.

(4) Applied to mutually rubbed parts

The member including the carbon nanotubes may be applied to the friction part. For example, the member including the carbon nanotubes may be applied to a gear, a compressor, or the like. Since the carbon nanotubes are excellent in strength as described above, when the carbon nanotubes are applied to the friction part, the wear resistance of the friction part may be improved.
