Abstract

The invention relates to a nano-silver conducting film as well as a preparation method thereof. The preparation method comprises the following steps: coating water-based graphene aqueous solution on the surface of a nano-silver conducting film, and forming an integrated black protective layer on the surface of the nano-silver conducting film after the coated aqueous solution is dried. The nano-silver conducting film provided by the invention has the advantages that the graphene protective layer not only realizes protective effect on the nano-silver conducting film but also solves the problem that the nano-silver conducting film is yellowish, and integrated black effect of a touch screen is improved.

Description

technical field [0001] The invention relates to a nano-silver conductive film and a preparation method thereof, in particular to a preparation method of a nano-silver conductive film with improved color system. Background technique [0002] With the rapid development of electronic information technology and artificial intelligence technology, electronic products tend to be smaller, softer and lighter. Therefore, flexible and wearable electronic products are increasingly widely used in various fields, such as in solar panels, touch displays, organic light-emitting diodes, etc. In recent years, a lot of research work on flexibility and high conductivity has been reported. Flexible conductive materials based on graphene, fullerene, carbon nanotubes, conductive polymer materials and metal nanomaterials have become research hotspots. Among them, silver nanowire (AgNWs)-based transparent conductive film has become a material that is very likely to replace the traditional ITO tra...
