Defogging device with carbon nanotube film

摘要

A defogging device for reducing fog on a surface of a substrate, which comprises a power unit and a heating element. The heating element is attached to the substrate, which comprises at least one carbon nanotube film comprising carbon nanotubes arranged substantially parallel to each other. The heating element transforms electricity into heat to vaporize fog of the first surface of the substrate when the heating element is connected to the power unit.
