Abstract
Transparent TiO2 nanoparticle/polymer hybrids were synthesized from titanium isopropoxy methacrylate via hydrolysis and polymerization in 2-methoxymethanol. Crystalline TiO2 nanoparticles were uniformly dispersed in the polymer matrix. A highly transparent free-standing TiO2 nanoparticle/polymer hybrid film was synthesized. The refractive index (RI) of the hybrid films on Si substrates could be controlled by varying the concentration of TiO2 nanoparticles: the RI increased with increase in Ti content. A further increase in the RI was achieved upon irradiation with ultraviolet light. A TiO2 nanoparticle/PMMA hybrid without the silica component exhibited an RI of 1.717 and an Abbe number of 21.6.
