Preparation and Application of Silver Nano Composite Fibers by Electrostatic Spinning

银纳米粒子由于其特殊的物理化学性质而被广泛应用,但其易团聚,影响实际使用效果。银纳米粒子可被负载到稳定载体上,获得具有优异性能的纳米复合材料,克服了团聚等缺限,大大改善应用效果和效率。采用静电纺丝技术制备银修饰纳米复合纤维材料是其中一种有效的方法,近年来在复合材料制备领域受到了广泛关注。本文综述了最近几年关于静电纺丝制备负载银纳米颗粒纤维复合材料及其应用的研究进展,重点介绍了静电纺丝制备负载银纳米纤维过程中纳米银的生成和负载方法,总结了有机主体和无机主体两种纺丝纤维的制备研究进展,详细介绍了负载银纺丝纤维在几个重要领域的应用及研究方向。

Silver nanoparticles have been widely applied in various areas due to their special physical and chemical properties. However, the practical applications are always restricted by aggregation between nanoparticles. The drawbacks can be minimized by dispersing nanoparticles onto a template to generate nanocomposites. The obtained nanocomposites have much better physical and chemical properties over the single component. Electrostatic spinning has already been used as an effective tool to synthesize the nanofiber composites loaded with silver nanoparticles. In this paper we reviewthe studies about synthesis and application of silver nanocomposites by electrostatic spinning in recent years,highlighting the preparation and loading methods of Agnanoparticles in the process of synthesizing silver composite fibers. The recent developments in the preparation of two kinds of silver composite fibers,organic and inorganic composite fibers,are summarized. In addition,the paper also point out the directions.
