Problems solved by technology

However, indium tin oxide has many disadvantages: brittleness, expensive vacuum deposition technology, less and less indium reserves, increasingly expensive prices, etc.
At present, there are people who use preservatives to solve the above problems, but preservatives are expensive and most of them are toxic
At present, there is no report on the use of solution method to improve the chemical stability of silver nanowire transparent conductive film

Abstract

The invention discloses a method for improving chemical stability of a silver-nanowire transparent conductive film through the solution method. According to the method, the prepared silver-nanowire transparent conductive film is placed into a sodium borohydride (NaBH4) aqueous solution of certain concentration to be soaked for certain time, then placed into a ferric trichloride (FeCl3) aqueous solution of certain concentration to be soaked for certain time after being cleaned and dried by an air blower after being cleaned, and therefore the chemical stability of the silver-nanowire transparent conductive film can be improved. The method is easy to operate, low in cost and suitable for large-scale production.

Description

technical field [0001] The invention relates to a method for improving the chemical stability of a silver nanowire transparent conductive film, in particular to a method for improving the chemical stability of a silver nanowire transparent conductive film by using a solution method. Background technique [0002] Transparent electrodes have become important components in modern optoelectronic devices (solar cells, organic light-emitting diodes, displays, touch screens, etc.). The most commonly used transparent electrode material is indium tin oxide (ITO). However, indium tin oxide has many disadvantages: brittleness, expensive vacuum deposition technology, dwindling reserves of indium, and increasingly expensive prices. Therefore, it is necessary to find alternative materials for ITO. At present, materials that can replace ITO and are suitable for flexible devices include carbon nanotubes, graphene, and silver nanowires. Although many researchers are working on conducting ...
