Abstract

The invention discloses a packaging and manufacturing method of a highly stable silver nano-wire composite film. The method is characterized by firstly, coating a silver nanowire dispersion liquid on a substrate so as to form a network-shape silver nanowire structure; and then using a silver nanowire welding liquid to soak or infiltrate the substrate so that silver nanowires forming the network-shape silver nanowire structure react at a mutual superposed position and local mutual dissolution is generated; therefore, realizing mutual welding; and finally, through light curing resin packaging, acquiring the silver nano-wire composite film. In the invention, chemical welding processing is performed on the network-shape silver nanowires formed through bridging so as to obtain a stable structure; simultaneously, a light curing resin is used as a packaging layer; and ultraviolet irradiation is used to generate an insoluble film. A film material acquired through the method in the invention has high transmittance, a low square resistance, good stability and a high antioxidant capability.

Description

technical field [0001] The invention relates to a transparent conductive film, in particular to a method for encapsulating and preparing a silver nanowire composite film. Background technique [0002] At present, silver nanowires have broad application prospects due to their unique optical and electrical physical properties, such as thin-film solar cells, touch screen displays, light-emitting diodes, and flexible thin-film displays. In addition, silver nanowires have excellent electrical conductivity, strong adsorption capacity, good biocompatibility and other special properties unmatched by other materials, and are used to prepare transparent conductive films to replace traditional indium tin oxide (ITO) transparent electrode material. [0003] Due to the gradual increase in the use of traditional indium tin oxide, the ore reserves of indium tin oxide are not abundant enough, resulting in an increase in cost prices year by year. When indium tin oxide is used to prepare tr...
