FABRICATION OF TITANIA/POLYMER CORE-SHELL NANOPARTICLE AND APPLICATION FOR TRANSPARENT THIN FILM POLYMER NANOCOMPOSITE WITH HIGH REFRACTIVE INDEX

摘要

The present invention is titania / polymer core - relates to the manufacture of the cell nanoparticles, titanium oxide nanoparticles the in-core (core) component, and dispersed in an aqueous solution after a predetermined amount of titanium oxide nanoparticles, by using a silane coupling agent to the dispersed titanium oxide nanoparticles after modifying the surface hydrophobic, by introducing additional monomer and initiator core by coating the surface of the titanium dioxide nanoparticles to the polymer formed in the cell (shell) component using a seed polymerization takes place but not limited to the surface of the titanium oxide nanoparticles at an appropriate temperature and time - method for producing a cell nanoparticles provides. ; According to the present invention, a simple and inexpensive process by using the titania / polymer core - has the advantage that can be easily produced in a cell nanoparticles. Furthermore, the core, which may be prepared in the present invention as well as cells nanoparticles not be bound by the size and shape of the core component, the type of the polymer cell, it is possible without restrictions on thickness prepared. Seen from the process point of view, this reaction is conducted in a non-volatile solution, has the advantage of mass production and the recovery of the nanocomposite that is easy. In addition, the titanium oxide / polymer core-shell nanoparticles with a polymer by mixing the titanium oxide / polymer core-time cell hayeoteul nanomaterial manufacturing a polymer thin film containing the composite material, the transparency is not reduced compared to the conventional polymer film, the refractive index proposes the improved characteristics.
