Abstract

The invention discloses a transparent electrode and a preparing method of the transparent electrode. The transparent electrode and the preparing method of the transparent electrode are characterized in that the transparent electrode is formed by attaching a silver nanowire and a zinc oxide nanowire to a transparent substrate through a monolayer structure in a mixing and assembling mode. The silver nanowire and the zinc oxide nanowire are effectively compounded to form the monolayer structure. With the compound structure, the nanowire and the zinc oxide nanowire are connected on the two-dimensional dimension, and the performance of a compound film is superior to any film under the synergistic effect of the nanowire and the zinc oxide nanowire. The structure is mainly achieved through self nano assembly, the means of high-temperature solidifying, high-pressure forming and the like are combined, and the transparent electrode can be widely applied to transparent substrates such as glass substrates and PET substrates. Compared with a zinc oxide film and a silver nanowire single-structure film, the transparent electrode with the structure has the excellent performance of being smooth and even in surface, high in electric conductivity, good in light permeating performance, low in haze and the like, and the obtained transparent electrode can be widely applied to various circuit devices.

Description

technical field [0001] The invention belongs to the field of conductive materials, in particular to the field of optoelectronic devices. Background technique [0002] Transparent conductive films are essential key components for optoelectronic devices. The transparent conductive material in the current market is mainly indium tin oxide (ITO). Due to the limited amount of metal indium that can be mined, it is an important strategic resource. At the same time, the ductility of ITO is insufficient to meet the requirements of flexible devices. Therefore, the development of indium-free transparent conductive films to replace ITO has become a bottleneck problem that needs to be solved urgently in the field of optoelectronic devices. [0003] At present, a large number of international scientific research groups are in need of ITO substitutes. Nano-organic films, nano-metal films, nano-carbon-based films and nano-oxide films are considered to be the most promising alternative m...
