Embodiment 1

[0014] The PDMS substrate was plasma treated for 3s, placed on the printing platform and heated to 55°C. The control point spacing is 50μm, the line spacing is 1000μm, and a silver grid is printed on the processed PDMS substrate. Place on the heating table and anneal at 120°C for 1h. After cooling, the dot pitch was controlled to 40 μm, and a layer of PEDOT:PSS doped with 6% ethylene glycol and 2% surfactant was printed on it. Place on the heating table and anneal at 120°C for 15 minutes.

Embodiment 2

[0016] Place the PET on the printing platform and raise the temperature to 55° C., control the dot pitch to 50 μm and the line pitch to 1000 μm, and print a silver grid on it. Place on the heating table and anneal at 120°C for 1h. After cooling, the dot pitch was controlled to 40 μm, and a layer of PEDOT:PSS doped with 6% ethylene glycol and 2% surfactant was printed on it. Place on the heating table and anneal at 120°C for 15 minutes.

Embodiment 3

[0018] The PDMS substrate was plasma treated for 3s, placed on the printing platform and heated to 55°C. The control point spacing is 50μm, the line spacing is 1000μm, and a silver grid is printed on the processed PDMS substrate. Place on the heating table and anneal at 120°C for 1h. After cooling, the dot pitch was controlled to 40 μm, and a layer of ZnO nanoparticle dispersion was printed on it. Place on the heating table and anneal at 120°C for 15 minutes.

Abstract

The invention discloses a flexible transparent silver grid composite electrode and a production method thereof. The electrode structure is as follows: A/ a silver grid/ an elastic substrate. The A can be conductive polymer (PEDOT:PSS), a metal-oxide-semiconductor (ZnO), and a binary complex of the above mentioned materials. The substrate adopts high elasticity plastics, such as polyethylene terephthalate (PET), polyimide (PI), polyvinylalcohol (PVA), polydimethylsiloxane (PDMS), polyurethane acrylate(PUA), and hydrogel, and so on. The production method is characterized in that the metal grid and the A material are sequentially printed on the high elasticity plastic substrate by adopting the ink-jet printing technology. The produced transparent electrode is advantageous in that the comprehensive performance is excellent, the square resistance is low, the flexibility is good (the electrode can be bent, distorted, and even stretched at will), the surface is leveled, the oxidation-resistant capability is strong, and the shape and the size can be adjusted at will.

Description

Technical field [0001] The invention relates to a flexible transparent silver grid composite electrode and a manufacturing method thereof, and belongs to the field of photoelectric information materials and applications. Background technique [0002] With the emergence of flexible, portable, low-cost and exquisite wearable electronic products, electrodes as an important part of it require not only excellent optoelectronic properties, high flexibility, flat surface, superior chemical stability, low-cost production, but also Controlled patterning production and any adjustable size. However, at present, there is no electrode with the above characteristics. Summary of the invention [0003] Technical problem: In order to overcome the above-mentioned shortcomings of the prior art and better meet the development of future wearable electronic products, the present invention provides a flexible transparent silver grid composite film electrode with excellent comprehensive performance and ...
