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 review the studies about synthesis and application of silver nanocomposites by electrostatic spinning in recent years,highlighting the preparation and loading methods of Ag nanoparticles 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.
