Embodiment

[0015] 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;

[0016] A layer of removable adhesive (purchased on Alibaba) was applied to the protective film with a Gardco Automatic Drawdown Machine DP8301 sheet coater. 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;

[0017] 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 thread cont...

Abstract

The invention discloses a silver nanowire transparent conductive film with multiple protections. The preparation steps are as follows: cleaning the protective film; coating a layer of adhesive with low adhesion on the protective film and drying it with an infrared lamp; The silver nanowire conductive ink is coated on the protective film, and the silver conductive network is obtained after drying; a layer of conductive substance is coated on the silver conductive network; a high-adhesion adhesive is coated on the silver conductive network, and then the The substrate is placed flat on the adhesive, and dried to obtain a transparent conductive film of silver nanowires with multiple protections. The silver transparent conductive film prepared by the method has multi-layer protection and can be stored for a long time; it has good adhesion to the substrate, high conductivity, high light transmittance, and the protective film can be easily torn off, and can be used in many applications in the electronic information industry. aspect.

Description

technical field [0001] The invention belongs to the technical field of transparent conductive films, in particular to a silver nanowire transparent conductive film with multiple protections. Background technique [0002] Silver is widely used in many aspects due to its excellent electrical and thermal conductivity, such as conductive silver glue, etc. Silver nanowires are important conductive materials in fields such as touch screens and semiconductor devices. Compared with commonly used metal oxide conductive materials, silver nanowires overcome the shortcomings of metal oxides such as brittleness and low conductivity. Compared with graphene and carbon nanotubes, which are currently being researched hotly, silver nanomaterials are cheaper and are currently the most likely breakthrough conductive material. For the application of silver nanowires, it must first be formulated into silver conductive ink, and then prepared into a thin film. In the previous preparation of silv...
