Abstract

The invention relates to the technical field of nano materials, and specifically relates to a preparation technology of silver nanowires with small diameter and high length-diameter ratio. The preparation technology lies in that under the effect of a seed crystal solution and an inductive agent, a reduction reaction between a reducing agent and a silver source compound is promoted and the silver nanowires are generated under the assistance of a template compound, in an aqueous solution system consisting of the template compound, the reducing agent and the silver source compound. The prepared silver nanowires have relatively high length-diameter ratio and good performances; and the preparation technology is simple.

Description

technical field [0001] The invention relates to the technical field of nanomaterials, in particular to a preparation process of silver nanowires with thin diameter and high aspect ratio. Background technique [0002] The surface effect, small size effect and quantum tunneling effect of silver nanowire materials have special functions that macroscopic silver materials do not have, as well as the unique length-to-diameter ratio and flexibility of fibers, making silver nanowires in optics, heat, electricity, The properties of magnetism, mechanics and chemistry have been significantly improved, so the application of silver nanowire materials has become more and more extensive, and more and more attention has been paid to them. The demand for silver nanowire materials in the market is also increasing. In recent years, the application and research of silver nanowires on transparent conductive films have attracted more and more attention (see US patent20110024159 & Adv.mater.2011, ...
