Abstract

The invention relates to a carbon nanotube fabric and a heating body using the carbon nanotube fabric. The carbon nanotube fabric comprises a heating element and at least two electrodes, wherein the at least two electrodes are arranged at intervals and are electrically connected to the heating element; the heating element comprises a plurality of carbon nanotubes which are connected end to end; and the at least two electrodes are electrically connected to the carbon nanotubes in the heating element. The carbon nanotube fabric can be applied in the fields of shoe pads, heat insulation clothing, electric blankets, physical therapy instruments and the like.

Description

technical field [0001] The invention relates to a fabric and a heating element using the fabric, in particular to a fabric that can be used for heating and a heating element using the fabric. Background technique [0002] Existing fabrics that can be used for heating generally include a heating element and at least two electrodes. The at least two electrodes are arranged on the surface of the heating element and are electrically connected to the heating element. When a voltage or current is applied to the heating element through the electrode, due to the high resistance of the heating element, the electric energy passed into the heating element is converted into heat energy and released from the heating element, thereby realizing heating. In the prior art, a heating element formed by braiding of metal wire or carbon fiber is usually used for electrothermal conversion. However, the strength of the metal wire is not high and it is easy to break, especially when it is bent or ...
