Problems solved by technology

However, the one-dimensional silver nanostructures synthesized by wet chemical methods are limited to silver nanowires, and the research on the preparation of silver nanobelts is relatively rare (B.Q.Liu, W.Luo, X.P.Zhao., Mater.Res.Bull.2009, 44, 682-687. Yugang Sun, Brian Mayers, Younan Xia..Nano letters, 2003, 3, 675-679), and the solution method either needs to use a hard template such as alumina, or needs to use a surfactant (such as polyethylene Pyrrolidone) as a structure-directing agent, the preparation process is extremely cumbersome, and generally requires a complicated follow-up template removal process, and the yield is low
This laboratory preparation method is not conducive to the large-scale industrial application of silver nanoribbons

Abstract

The invention belongs to the technical field of novel materials, in particular to a preparation method of silver nanobelts. In the method, silver nitrate is taken as a metal salt precursor, water is taken as the solvent and aminoanisole is taken as the reducing agent to react in a hydrothermal reactor for 1-24 hours at 100-240 DEG C to obtain the silver nanobelts which have thickness of 20-100 nanometers, width of 100-1000 nanometers and length of 1-100 micrometers and are protected by poly-aminoanisole. The silver nanobelts prepared by the invention have controllable topography and adjustable size besides high specific surface, the characteristic of common nano materials, and are expected to be widely applied in such fields as conducting materials, electromagnetic shielding, static resisting, sterilization, surface enhanced Raman light, electricity and the like and novel composite materials.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a preparation method of silver nanobelts. Background technique [0002] Nanomaterials are one of the hot spots in the research of new material technology in this century. Since silver nanoribbons have the minimum scale properties required for efficient electron transport and photon excitation, the research on them has gradually become a hot spot. In addition, it has attracted the attention of a large number of researchers due to its unique electronic, optical, thermodynamic and mechanical properties and its potential applications in electronics, photonics, biochemical sensing, imaging and catalysis. [0003] In recent years, the wet chemical reduction method has been widely used in the preparation of silver nanostructure materials due to its simplicity and mildness, easy regulation, uniform product, and large-scale preparation (M.Rycenga et al. Adv.Mater.2008, ...
