Embodiment
[0014] Choose a thinner PET film as the protective film. Tear off the film on the protective film, then put the protective film in a beaker filled with ethanol, and clean it ultrasonically for 10 minutes. Then put the film on the baking platform and bake for 5 minutes with an infrared baking lamp;
[0015] A layer of removable adhesive (purchased on Alibaba) was applied on the protective film with a Gardco Automatic Drawdown Machine DP8301 sheet coating machine. Strictly control the amount of coating, so that the thickness of the final bonding layer is about 10-30nm. Then bake with an infrared baking lamp for 5 minutes;
[0016] The silver nanowire conductive ink is coated on the protective film, and then vacuum-dried in a vacuum oven at 110° C. for 10 minutes to obtain a silver nanowire network with a thickness of about 200 nm. The silver nanowire ink is homemade. The diameter of the silver nanowire is between 30-50nm, and the length is between 10-20μm. The ink silver th...

Abstract
The invention discloses a preparation method of a tear-and-play silver nanowire transparent conductive film, comprising the steps of: cleaning a protection film; coating a layer of binders of low bonding strength on the protection film, and performing drying by infrared lamps; coating silver nanowire conductive ink on the protection film, and obtaining a silver conductive network after drying; and coating a binder of high bonding strength on a substrate, keeping flat the protection film above the substrate, and performing drying to obtain the tear-and-play silver nanowire transparent conductive film with the protection film. The tear-and-play silver nanowire transparent conductive film prepared in the method has long-term dual protection, can be kept for a long period, has the characteristics of high conductivity and light transmittance; the substrate possesses high binding strength, and the protection film is easy to tear out; the tear-and-play silver nanowire transparent conductive film can be used in various aspects of the electronic information industry.
Description
technical field [0001] The invention belongs to the technical field of transparent conductive films, and in particular relates to a ready-to-use and tear-off silver nanowire transparent conductive film and a preparation method thereof. Background technique [0002] At present, wearable devices are becoming more and more popular and the market size is getting bigger and bigger, which will become an area that the consumer electronics market will focus on in the future. However, at present, most wearable devices are still in the experimental stage, and there is still some distance from commercialization. The main obstacle limiting its commercialization is that its components cannot be 100% flexible. Among them, one of the biggest shortcomings is the conductive substrate. The commonly used conductive substrate is indium tin oxide (ITO), but the brittleness of this type of oxide makes it unsuitable for building flexible substrates. In order to prepare flexible conductive subst...
