Title:
NANOPARTICLE-POLYMER FLUORESCENT COMPOSITE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/222200
Kind Code:
A1
Abstract:
The present invention provides a nanoparticle fluorescent composite and a preparation method therefor. The nanoparticle fluorescent composite preparation method comprises the steps of: preparing magnetite (Fe3O4) nanoparticles; forming a nanoparticle composite by mixing the magnetite (Fe3O4) nanoparticles, an organic polymer comprising an aliphatic carbon chain and a solvent dissolving the organic polymer so as to prepare a precomposite, and by drying the precomposite; and emitting pulsed laser at the nanoparticle composite so as to convert the magnetite (Fe3O4) nanoparticles into wüstite nanoparticles and provide conjugated polymer characteristics to the organic polymer.
