Abstract

The present invention belongs to the field of nanometer material preparing technology, and provides a two-step silver nanometer wire synthesizing process with high form selectivity and high efficiency. Under the protection of inert gas, very dilute ethylene glycol solution of silver nitrate is first added into ethylene glycol to prepare silver crystal seed; ethylene glycol solution of silver nitrate in relatively high concentration and ethylene glycol polymer solution in the corresponding concentration and volume are then added into the reaction system with crystal seed; and through crystal growth, silver nanometer wire is obtained. By means of regulating reaction condition, the size and form of the silver nanometer wire may be controlled. The present invention has low reaction cost and high silver nanometer wire yield, and the obtained silver nanometer wire has high purity, good structure and high mechanical performance.

Description

technical field

[0001] The invention relates to the technical field of nanomaterial preparation, in particular to a method for synthesizing silver nanowires. Background technique

[0002] One-dimensional nanomaterials, such as nanowires, nanofibers, nanorods, nanoribbons, etc., are widely used in nanoelectronic devices, nanometer Lasers, nanochemical and biological sensors, nanoprobes, nanocomposites, etc. Silver nanowires are the most important one-dimensional nanomaterials. Their excellent electrical and thermal conductivity and chemical stability also make silver nanowires play an important role in the construction of nanodevices. At present, there have been many literature reports on the synthesis of silver nanowires. According to the different principles, they can be roughly divided into the following categories: template method, polyol method, hydrothermal method, wet chemical method, biomimetic synthesis method, molecular self-assembly induction method, electrochemi...
