纳米空气净化材料

New Nanostructured Materials for Air Cleaning

概述了纳米材料在空气净化方面的应用与研究 ,按照是否发生了化学反应 ,将空气净化的过程分为化学过程和物理过程 ;介绍了包括纳米二氧化钛等一些新型纳米材料 ,它们以化学催化为主要手段进行空气净化 ,并且介绍了基于电纺丝等新技术发展起来的无纺纳米丝 ,及在普通过滤材料上的附着与层压得到的复合材料在空气净化中应用的进展。

In this paper, applications of nanostructured materials in air cleaning are summarized. Air cleaning can be divided into chemical process and physical process depending on whether chemical reactions take place. Some nanostructured materials are introduced which involve chemical reaction process in air cleaning, such as nanostructured titanium dioxide. Some other nanostructured materials, including materials only absorbing and holding up impurities in air cleaning, are introduced too. Also electrospinning fiber is briefly reviewed.
