Abstract
A vehicle and a building includes a window and a window film attached on the window. The window film includes a polymer film, a carbon nanotube film embedded in the polymer film, and a protective layer located on the polymer film. The carbon nanotube film includes a plurality of carbon nanotubes substantially aligned along the same direction. The carbon nanotube film is located between the protective layer and the polymer film.
