Transparent flexible electrode thin film, manufacturing method thereof and transparent flexible electrode

Abstract

The invention discloses a transparent flexible electrode thin film, a manufacturing method thereof and a transparent flexible electrode. The transparent flexible electrode thin film comprises a substrate, a modification layer and a metal nanowire in sequence, wherein the substrate is formed by a transparent flexible plastic thin film; the modification layer is formed by a water-soluble high-molecular polymer; and the metal nanowire is embedded into the surface of the modification layer. The transparent flexible electrode thin film has high conductivity, high bending property, high transmittance and high stability, thereby not only enhancing the interface adhesion of the metal nanowire, but also playing a colloid protection role when bearing stress.

Description

technical field [0001] The present disclosure generally relates to the technical field of electronic devices, and specifically relates to a transparent flexible electrode film, a manufacturing method thereof, and a transparent flexible electrode. Background technique [0002] With the relentless pursuit of human beings for visual enjoyment and improved life quality, transparent flexible displays and wearable and foldable electronic products have gained more applications in meeting the needs of individuation, diversification and complex conditions, which requires the functional layers of the corresponding products The material has high-strength structural stability, bending and folding ability, and requires stable preparation process and development performance of transparent flexible electrodes. [0003] The existing flexible transparent electrodes are usually prepared by vapor-deposited metal stacks, graphene, conductive polymer inks, indium tin oxide and other methods. ...

AI Technical Summary

Problems solved by technology

[0007] Others such as cheap screen printing conductive polymer inks can save more costs, but their conductivity is poor, the process is extremely cumbersome, and cannot be compared with metal films; recently, with the deepening of research, metal nanowires can simultaneously meet the needs of transparent and flexible displays. High light transmittance and high conductivity and other characteristics requirements, but it is a one-dimensional linear structure after film formation on the substrate, the elasticity is relatively poor, the adhesion on the substrate is relatively small, and it is easy to break when the bending degree is large

[0008] In addition, in the process of preparing transparent flexible electrode films, there are still many complex factors that need to be controlled in processes such as filling substances and thermal curing, the process is relatively complicated, and the process cost is relatively high.
