The present invention relates to a fiber-nanowire composite-based sheet having super-amphiphilic characteristics. In the present invention, fibers including metal nanoparticles or metal oxide nanoparticles embedded in the fibers or located on the surface of the fibers are synthesized, and a sheet based on a composite in which metal nanowires or metal oxide nanowires have been grown from the above fibers is provided. A sheet of the present invention has super-amphiphilic characteristics and can be used in various fields such as the antibacterial filter field, the antibacterial film field, the antiviral filter field, the antiviral film field, the antifouling coating field, the drug delivery vehicle field, or the water treatment filter field.

Super-amphiphilic fiber-nanowire composite and application

The present invention relates to a magnetic-optical composite nanostructure, which has a heterogeneous nature due to consisting of a first core-shell nanoparticle and second core-shell nanoparticles and thus realizes magnetic and optical functions at the same time.

Magnetic-optical composite nanostructure

Provided are a nanofiber-nanowire composite and a method for producing the same. The method includes preparing a nanoparticle using a dipolar solvent, producing a nanofiber-nanoparticle composite in an electrospinning synthesis solution including the nanoparticle through electrospinning, and growing a nanowire from the nanoparticle by hydrothermally synthesizing a dried nanofiber-nanoparticle composite.

Nanofiber-nanowire composite and preparation method therefor

Provided are a nanoparticle-polymer fluorescent composite and a method of preparing the same. The method includes preparing magnetite (FeO) nanoparticles, mixing the magnetite (FeO) nanoparticles, an organic polymer having an aliphatic carbon chain, and a solvent for dissolving the organic polymer to prepare a preliminary composite and drying the preliminary composite to form a nanoparticle polymer composite, and irradiating a pulse laser to the nanoparticle polymer composite to change the magnetite (FeO) nanoparticles to Wustite nanoparticles and providing conjugated polymer characteristics to the organic polymer.
