Studies on titanium oxide core, transparent polymer shell nanocomposite thin films

Abstract

Thin hybrid optical films of TiO2 – polystyrene were prepared by in situ polymerization followed by a spin coating technique. The styrene monomers were used for polymerization and cetyltrimethylammonium bromide (CTAB) as a surface modifier. Titanium n-butoxide (IV) was used to make the titania network. The FTIR results show the successful connection between organic and inorganic residues and the good dispersion of the PS segment in the titania network. The results of HRTEM suggest that titanium dioxide remains in hybrid materials prepared on the nanometer scale and of structure of core-shell. Hybrid-prepared films show possible applications in optical devices which have a very high optical transparency in the visible range.
