Title:
ALUMINUM OXIDE PROTECTED SILVER NANOWIRE TRANSPARENT ELECTRODE, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/142586
Kind Code:
A1
Abstract:
Disclosed are an aluminum oxide protected silver nanowire transparent electrode, a preparation method therefor and the use thereof. The method comprises: using an annealed silver nanowire transparent conductive film as a cathode, a platinum electrode as an anode, a silver/silver chloride electrode as a reference electrode and a solution containing aluminum nitrate nonahydrate as an electrolyte; electrodepositing an aluminum oxide protective layer on the silver nanowire transparent conductive film by means of the three-electrode system in a constant-voltage mode; rinsing same; and then annealing same to obtain the aluminum oxide protected silver nanowire transparent electrode. According to the present invention, the electro-deposition process is improved by controlling the reaction rate; aluminum oxide is accurately deposited on the surface of the silver nanowires without influencing a light-transmitting area; the contact between the silver nanowires is promoted by means of the deposition process; the light absorption of a coating layer is avoided via the high-flatness surface; the stability and the photoelectric properties are improved; a silver nanowire protection process is greatly simplified; the production cost of a flexible transparent electrode is greatly lowered; and the development of flexible electronics is promoted.
