Abstract

The present invention discloses a flexible transparent conductive electrode. The flexible transparent conductive electrode is formed by transparent flexible base materials and a silver nanowire coating layer covering the surface of the transparent flexible base materials. The preparation method of the flexible transparent conductive electrode comprises the following steps of: adding silver nanowire aqueous dispersion, waterborne acrylate resin, triethylene tetramine, 1-2 parts of methyl p-tolyl sulfone, 0.1-0.3 parts of hydrogenated castor oil and mixed solvent into a vacuum mixer for vacuum defoamation and uniform mixing to obtain mixed liquor, wherein the concentration of the silver nanowire aqueous dispersion is 2-10 mg/mL, and the mixed solvent is made by mixing alcohols solvent and ketones solvent; drying a wet film in a vacuum drying oven with 150 DEG C for 3-10 min, and taking out the wet film after the wet film is completely volatilized, namely obtaining the flexible transparent conductive electrode. The flexible transparent conductive electrode reduces the conductive resistance rate, further avoids stacking of the silver nanowires, ensures the conductive uniformity and improves the light transmittance.

Description

technical field [0001] The invention relates to the technical field of silver nanowires, in particular to a flexible transparent conductive electrode. Background technique [0002] Metal oxides, especially ITO, have high light transmittance and low resistivity in the visible region, and have been a hot spot in the research and application of transparent conductive electrodes in the past 50 years. However, the metal oxide itself has limited conductivity, and is brittle and fragile, not easy to deform and other defects. At the same time, raw material resources are increasingly scarce and expensive, which can no longer meet the needs of the development of modern optoelectronic devices. In recent years, with the development of micro-nano technology, transparent A new field opened up by conductive electrodes is two-dimensional micro-nano new materials and thin-film electrodes, such as polymer conductive films, carbon nanotube films, graphene films and metal nanowire films. Graph...
