However, this method is to coat the hydrazine hydrate aqueous solution dilution on the surface of the conductive layer. According to the conductive film of different square resistance, the requirements on the concentration of hydrazine hydrate and the coating speed are strict. Color correction effect; at the same time, hydrazine hydrate is easy to smoke in the air, has an ammonia smell, and can form an azeotrope with water under certain conditions, which is harmful to production personnel, poor in use safety, and cannot be used for industrial production

Abstract

The invention discloses a method for reducing yellowness of a silver nanowire transparent conductive film through changing plasma resonance intensity. Water / alcohol soluble phenol is added in the conductive ink so as to be combined with the surface PVP of the silver nanowire by forming hydrogen bonds to suppress silver nanowire surface plasma resonance, and thus the yellowness value of the conductive film can be reduced. The protective layer containing the phenolic compound can also be further arranged on the conductive layer to form the hydrogen bonds with the remaining PVP on the surface ofthe silver nanowire so as to further reduce the yellowness value. With application of the method, the b* value of the obtained conductive film is reduced to 0.8 so that the problem of high yellownessvalue of the conductive film can be completely solved, and display has no chromatic aberration if the conductive film is manufactured into the display screen.

Description

technical field [0001] The invention relates to the display field, in particular to a method for reducing the yellowness of a nano-silver wire transparent conductive film. Background technique [0002] In recent years, with the rapid development and updating of electronic products, the demand for large-size and high-definition displays has continued to increase, such as smart blackboards, industrial monitors, outdoor displays and other large-size equipment, as well as solar cells, etc. The demand for transparent conductive films has exploded ; At the same time, the requirements for transparent conductive films are also constantly increasing, for example, large-scale equipment requires low square resistance, and the requirements for optical performance are gradually improved. [0003] At present, the transparent conductive film for industrial applications is mainly ITO (indium tin oxide), but with the continuous development of indium ore resources, indium resources are gradua...
