Embodiment Construction

[0037]According to an exemplary embodiment of the present disclosure, the nanofiber-nanoparticle composite is synthesized in an electrospinning synthesis solution into which nanoparticles are injected. Nanofiber-nanoparticle composites are transformed into end-product nanofiber-nanowire composites by growing nanowires from nanoparticles exposed to the surface of the nanofiber-nanoparticle composite via a hydrothermal process. Nanofibers can be easily produced by a hydrothermal method after obtaining nanofiber-nanoparticle composites (in which nanoparticles are uniformly contained) by electrospinning an electrospinning synthesis solution in which nanoparticles are uniformly distributed- nanowire composites.

[0038] According to the exemplary embodiment of the present disclosure, no additional processing, such as heat treatment, performed in conventional methods is required. That is, it is possible to produce composites with higher productivity and uniformity than those produc...

Abstract

Nanofiber-nanowire composites and methods for their production are provided. The method comprises preparing nanoparticles using a dipolar solvent, producing a nanofiber-nanoparticle composite by electrospinning in an electrospinning synthesis solution containing the nanoparticles, and hydrothermally synthesizing the dried nanofiber-nanoparticle composite matter, growing nanowires from nanoparticles.

Description

technical field [0001] The present disclosure relates to nanocomposites, and more particularly to composites produced by synthesizing nanofibers comprising metal oxide nanoparticles into a biodegradable polymer solution, and growing metal from the nanofibers by a hydrothermal method oxide nanowires. Nanocomposites can be applied in various fields such as photocatalysts, sensors, beauty care, gene transfer and therapy. Background technique [0002] Nanofibers have structures with a diameter of about 1 μm or less. Nanofibers have a light specific gravity and have a very large surface area per unit mass and fine spaces. Nanofibers have been used in various fields such as aerospace industry, fuel cells, capacitors, batteries, drug delivery and biosensors. In particular, due to their very high compatibility with cells, biodegradable nanofibers are used in various fields, including medical fields (such as sutures, tissue regeneration, biosensors, drug delivery, and stem cell cu...
