Embodiment 1

[0021] In order to simplify the preparation process of the electrothermal film and ensure that the electrothermal film has good electrothermal effect and good bending performance, the embodiment of the present invention provides a conductive ink. The conductive ink includes a conductive filler, an elastic binder and a system solvent, wherein the conductive filler includes a zero-dimensional conductive material OD, a one-dimensional conductive material 1D and a two-dimensional conductive material 2D.

[0022] When the conductive ink provided by the embodiments of the present invention is applied to the electrothermal film, it is only necessary to print or coat the conductive ink on the surface of the flexible structure to form the electrothermal film layer on the surface of the flexible structure. The electrothermal film layer is dried to volatilize the system solvent in the electrothermal film layer, and an electrothermal film can be formed on the surface of the flexible struct...

Description

technical field [0001] The invention relates to the technical field of electrothermal film, in particular to a conductive ink, a preparation method thereof, and an electrothermal film. Background technique [0002] Physical therapy and health products such as electric carpets and heated mattresses are equipped with electric heating structures inside. After the electric heating structure is energized, the electric heat can be converted into heat energy, thereby achieving the effect of physical therapy and health preservation. Flexible physical therapy and health care products will be deformed such as extrusion, stretching, twisting, and wrinkles during use, making the electrothermal structure vulnerable to damage when the physical therapy and health care products are deformed. Therefore, the electrothermal structure needs to have good elasticity and deformation properties. [0003] In the prior art, an electrothermal fiber with good conductivity, cycle stability and stretchab...
