Abstract:
1. A vehicle, comprising: at least one defrost window, comprising: a transparent substrate having a top surface; at least one carbon nanotube film attached on the top surface of the transparent substrate, the at least one carbon nanotube film comprising a plurality of carbon nanotubes; a plurality of first electrodes and a plurality of second electrodes electrically connected to the at least one carbon nanotube film and spaced from each other, wherein the plurality of carbon nanotubes of the at least one carbon nanotube film is substantially aligned along a direction from the plurality of first electrodes to the plurality of second electrodes, and the plurality of first electrodes and the plurality of second electrodes are extended from vehicle bottom to vehicle top; a protective layer covering the at least one carbon nanotube film; and an electrical source electrically connected between the plurality of first electrodes and the plurality of second electrodes, the electrical source being adapted to apply electrical currents to the at least one carbon nanotube film; a control system electrically connected to the electrical source, the control system being adapted to control voltages of the electrical source; a switch electrically connected to the control system; a sensor electrically connected to the control system the sensor being adapted to detect frost on the defrost window.
