Abstract

The invention provides a silver nanowire containing a polyphenol compound and a preparation method and application thereof. The silver nanowire containing the polyphenol compound is prepared from the following raw materials: polyvinylpyrrolidone, bromine salt, silver salt and the polyphenol compound. According to the silver nanowire, on the basis of typical polyhydric alcohol synthesized silver nanowires, the polyphenol compound is introduced to serve as a reducing agent, the reduction rate of the reaction is increased, the high-pressure condition is not needed, and operation is easy; and the polyphenol compound is introduced as the reducing agent, so that silver ions can be subjected to a reduction reaction at a lower temperature, the transverse growth of silver is inhibited, and the generation of the silver nanowire with a smaller diameter is facilitated.

Description

technical field [0001] The invention belongs to the field of optoelectronic technology, in particular to a silver nanowire containing a polyphenol compound and its preparation method and application, especially to a silver nanowire containing a polyphenol compound prepared from a polyphenol compound and its preparation method and application . Background technique [0002] With the continuous development of electronic equipment in the direction of flexibility, flexible transparent conductive materials have become a research hotspot. Transparent conductive films are widely used in electronic products such as touch screens, light-emitting diodes, and solar cells, and have great application prospects. Currently, the most commonly used material for preparing transparent conductive films is indium tin oxide (ITO). ITO contains rare metal element indium, which is expensive and toxic, which increases the preparation cost. Therefore, next-generation flexible transparent materials...
