9 Claims

1. A method of manufacturing a fiber-nanowire composite-based sheet, comprising the steps of:

electrospinning an electrospinning solution including metal nanoparticles or metal oxide nanoparticles and a polymer and thus preparing a fiber-nanoparticle composite;

adding the fiber-nanoparticle composite to a nanowire synthesis solution containing metal ions and then performing sonication; and

growing metal nanowires or metal oxide nanowires from metal nanoparticles or metal oxide nanoparticles located inside and/or on the surface of the fiber-nanoparticle composite,

wherein the sonication is performed at an intensity of 1 kHz to 100 kHz for 1 second to 600 seconds.
