Abstract

The invention provides a method for preparing nanometer silver wires. The method includes the following steps of firstly, dissolving water-soluble high molecular polymers in a silver salt solution, and then adding an additive into the solution to obtain a spinning solution; secondly, conducting electrostatic spinning on the spinning solution to obtain nanometer fibers; thirdly, conducting deoxidation on the nanometer fibers to obtain the nanometer silver wires. The additive comprises butyl titanate and acetylacetone, wherein the volume ratio of the butyl titanate to the acetylacetone is 1:0.5-5. The method is easy to operate and high in controllability, and the nanometer silver wires prepared through the method are the same in size, excellent in bending resistance performance and capable of being widely applied to various transparent conducting materials.

Description

Technical field [0001] The invention belongs to the technical field of nano material preparation, and specifically relates to a preparation method of nano silver wires. Background technique [0002] As a nano-scale wire, nanowire is a one-dimensional structure that is limited to 100 nanometers or less in the horizontal direction (there is no limitation in the vertical direction). In addition to the excellent electrical conductivity of silver, nano-silver wires also have excellent light transmittance and bending resistance due to the nano-level size effect, so they are considered to be the most likely alternative to traditional indium tin oxide (ITO) The material of the transparent electrode. Compared with traditional ITO transparent conductive materials, nano-silver wires have the advantages of low consumption and low price, so they can be widely used in various transparent conductive materials, such as flexible solar cells, capacitive screen conductive materials, etc., so as to...
