Embodiment

[0020] PET was used as the substrate. Tear off the protective film on the new substrate, put it into acetone and ethanol and sonicate it for 5 minutes respectively. Then dry it with an infrared oven lamp. Then put it into the plasma cleaner and vacuum clean it for 5 minutes;

[0021] Cut the DJB-823 solid film protective agent into powder, weigh 0.5-2 g, and add it into 100 ml of mixed solvent (No. 120 solvent gasoline 60%, n-butanol 40%). Heat to 55-65°C in a water bath with gentle stirring for 10 minutes. After the protective agent is completely dissolved into a clear solution, keep the temperature of the water bath at 50-65°C for use;

[0022] On the processed substrate, a layer of DJB-823 solid film protectant solution was coated with a Gardco Automatic Drawdown Machine DP8301 sheet coating machine. Then, it was first baked with an infrared baking lamp for 5 minutes, and then dried in a vacuum oven at 100° C. for 10 minutes under vacuum. Obtain a bonding layer with a ...

Abstract

The invention discloses a method for preparing an ultra-high protection silver conductive film. The preparation steps are: cleaning, drying and plasma treatment of the substrate; coating a layer of DJB-823 solid film protective agent on the substrate, and drying Dry; apply silver nanowire conductive ink on the adhesive layer, and obtain a silver conductive network after drying; apply DJB-823 solid film protective agent on the conductive network, and obtain an ultra-high protective conductive film after drying . The conductive film uses DJB‑823 solid film protective agent, which won the “Second Prize of the National Invention Award” and is widely used in aerospace and military supplies, so that the film can maintain good resistance to a variety of environmental stimuli and at the same time make the film Its various performances have reached excellent levels and can be widely used in the field of electronic information.

Description

technical field [0001] The invention belongs to the technical field of transparent conductive films, and in particular relates to the preparation of an ultra-high protective silver conductive film. Background technique [0002] At present, the most used electrode material is indium tin oxide (ITO), and the material most likely to realize commercial flexible electrodes is silver nanowires. People formulate silver nanowires into ink, and then coat the ink on the substrate with primer bonding layer by spraying, scraping, rolling, etc., and finally coat the top coating protective layer on the silver nano network to obtain Silver conductive film. The use of primer and top coat greatly increases the protective performance of the silver conductive film and significantly improves the life of the film, making it closer to practical use. Common primer materials are mainly various resins, such as epoxy resin, acrylic resin, polyurethane and so on. Commonly used top coating materials...
