LAYERED DOUBLE HYDROXIDE OR MIXED METAL HYDROXIDE CAPTURING NANOPARTICLES AND MANUFACTURING METHOD FOR LAYERED DOUBLE HYDROXIDE OR MIXED METAL HYDROXIDE CAPTURING NANOPARTICLES

摘要

The present invention relates to a layered double hydroxide and a manufacturing method thereof and, more specifically, to the layered double hydroxide and mixed metal oxide catching nanoparticles and the manufacturing method thereof. The nanoparticle-layered double hydroxide composite of the present invention can be produced under mild conditions, be mass-produced and reduce production costs. Moreover, the properties of the composite can be controlled since the composite is manufactured by using synthetic nanoparticles in which physical properties including size etc are controlled. The nanoparticle-layered double hydroxide of the present invention can be used as a layered double hydroxide in various application fields including anion exchangers, catalyst supporters, electronic materials, optical coating materials, ultraviolet ray absorption bodies and optical catalyst etc and additionally has a property according to the interaction of the nanoparticles and parent materials catching the nanoparticles. A synthesized composite reduces the penetration of foreign materials like gas or moisture by forming a layered double hydroxide structure surrounding nanoparticles. The composite can prevent phase separation or aggregation when heat is applied by enlarging the spatial restriction power of nanoparticles in the composite. In a quantum dot nanoparticle-layered double hydroxide or a mixed metal oxide composite, a metal oxide or a layered double hydroxide acts as the surface protection layer of a quantum dot, thereby promoting a phenomenon such as the improvement of emission properties.;COPYRIGHT KIPO 2014;[Reference numerals] (AA) Divalent or trivalent metal cation;(BB) Hydroxyl ion;(CC) Nanoparticle having a functional group of negative charge;(DD) Composition unit of octahedron
