METHOD OF PREPARING TIO2/POLYMER CORE/SHELL NANOPARTICLE VIA PHOTOPOLYMERIZATION WITHOUT USING A INITIATOR

摘要

PURPOSE: A manufacturing method of titanium oxide/polymer core/shell nanoparticle is provided to manufacture massively titanium oxide/polymer core/shell nanoparticle through a photopolymerization using only the ultraviolet ray without using additional initiator. CONSTITUTION: The manufacturing method of titanium oxide/polymer core/shell nanoparticle includes following steps.(a) The titanium oxide nanoparticle is dispersed into a solvent.(b) A monomer is injected into the solvent with 'the dispersed titanium oxide'. A physical adsorption of the monomer is induced in the surface of the titanium oxide nanoparticle.(c) The ultraviolet ray is added to the surface of the titanium oxide nanoparticle with the adsorbed monomer. In the surface, a production of electrons and radicals is induced. In the surface, the polymerization of the monomer radical is induced.(d) The titanium oxide/polymer core/shell nanoparticle is collected from the polymerized solution through a precipitation.
