In order to fully understand the present invention and the objects achieved by the practice of the present invention, reference should be made to the accompanying drawings which illustrate embodiments of the present invention and the contents described in the accompanying drawings.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail by explaining embodiment of this invention with reference to attached drawing. Like reference numerals in the drawings denote like elements.

Transparent conductive film according to an embodiment of the present invention is an electrically conductive material (conductor), such as carbon nanotubes (carbon nanotube, CNT) and graphene (graphene) nano-carbon materials, or metal nanowires (metal nanowire) and metal Metal nanomaterials, such as a metal nanorod, can be used.

In the case of a transparent conductive film coated with a conductor on a plastic substrate without a binder, the mutual attraction between the conductor and the substrate is attached by a weak van der Waals' force, but the Scotch tape ( When the taping test is performed using a cellophane tape, adhesion between the conductive layer and the substrate is not secured by desorption between the conductive layer and the substrate.

However, since the transparent conductive film of the present invention can secure the adhesion between the conductor and the substrate through the local heating of the conductor without using a separate binder, the transparent conductive film of the present invention is a touch It can be used in device applications such as panels (or touch screens), flexible displays, flexible solar cells, and electronic paper.

The present invention uses selective electromagnetic heating of the conductive layer so that the substrate itself in contact with the conductive layer can act as a binder so that the substrate is locally temporarily melted and then physically bonded to the conductive layer while being hardened.

That is, when electromagnetic energy is applied to the substrate coated with the conductor for a suitable time, the conductive layer (conductor coating layer) including the conductor is selectively heated by electromagnetic waves (electromagnetic field), and the substrate in contact with the conductor is melted to form the substrate. Impregnated or adhered to the transparent conductive film is secured to secure the adhesion.

Therefore, since the transparent conductive film according to the embodiment of the present invention can bond or adhere the conductor and the substrate (flexible substrate) by using electromagnetic local heating of the conductor without a binder, the present invention provides a transparent electrode. Manufacturing costs can be reduced by simplifying the process and saving energy.

In order to use the transparent conductive film as a transparent electrode, an adhesive force must be secured between the conductive layers 30 applied to the flexible substrate 20 and the substrate 20. To this end, a binder (adhesive) 40 having excellent adhesion with the substrate 20 may be used. However, when the binder 40 is used, an energy consuming process may be necessary because a process of curing or drying the binder is required.

When the top coating of the binder material 40 as a protective layer and an adhesive layer of the transparent conductive film 10, which is a thin film of a conductor, an organic solvent is used. Since it is necessary, when manufacturing the transparent conductive film 10 (fabrication), a multi-step process is required, the process cost may be increased.
