纳米银的制备方法和应用现状

摘要

With the rise of nanotechnology in 21st century, nano-materials gradually entered the field of vision, and became the new area of nanomaterials.There are many preparation methods for nanomaterials, and the application fields are also very extensive.This paper chose nanometer silver as the representative of nanometer material, the preparation method was introduced by three categories:physical, chemical and biological, what's more, the application of the present situation and prospects of nano-silver in medicine, catalyst, agriculture, detection and other aspects were also introduced.%随着21世纪纳米技术的兴起, 纳米材料逐渐进入人们视野中, 进而开始了纳米材料的新时代.纳米材料的制备方法趋于多样化, 应用领域趋于广泛性.本文选用纳米银作为纳米材料的代表, 介绍其制备方法主要分为三大类:物理法、化学法和生物法.本文还详细介绍了纳米银在医学、催化剂、农业、检测等方面的应用现状和前景.
