Embodiment 1

[0043] See figure 1 , a flexible conductive film, including a flexible base material layer 1, a flexible conductive layer 2 and a flexible water vapor barrier layer 3, the flexible water vapor barrier layer 3 is arranged on one side surface of the flexible base material layer 1, and the flexible conductive layer 2 is arranged on the flexible water vapor barrier layer On the surface of layer 3 on the side away from flexible substrate layer 1, the specific preparation steps are as follows:

[0044]S1. Provide a flexible substrate layer 1 as a substrate. The flexible substrate layer 1 can be prepared by a screw extruder, which specifically includes melting the optical film particles required to form the substrate layer, and then extruding with a screw. The machine uniformly extrudes the base material layer material in the molten state to form a film-like flexible base material layer 1, and longitudinally or transversely stretches the formed flexible base material layer 1, so that...

The difference from Embodiment 1 and Embodiment 2 is that at this time, the flexible substrate layer 1 is located in the middle, and the flexible conductive layer 2 and the flexible water vapor barrier layer 3 are located on both sides of the flexible substrate layer 1 respectively, so that the flexible substrate layer 1 can be better protected from oxidation, corrosion, and the influence of the external environment. The specific preparation steps as follows:

[0057] S1. Provide a flexible substrate layer 1 as a substrate, and the preparation of the flexible substrate layer 1 is the same as that described in Embodiment 1 and Embodiment 2;

[0058] S2. Prepare the flexible conductive layer 2 and the flexible water vapor barrier layer 3 on both sides of the flexible substrate layer 1 respectively. The preparation me...
