| Abstract
| - A newly developed beads mill was used to create well-dispersed suspensions of TiO2 (titania) nanoparticlesin methyl methacrylate (MMA) and TiO2−PMMA nanocomposites were synthesized by subsequentpolymerization of the TiO2−MMA suspension. Beads milling successfully broke up titania nanoparticleagglomerates with the addition of the coupling agent (3-acryloxypropyl) trimethoxysilane (APTMOS) to thetitania−MMA suspension. Agglomerated particles were broken up into primary particles as small as 10 nmin suspensions with nanoparticle mass fractions as high as 0.05. Well-dispersed suspensions of titaniananoparticles had reduced UV transmission but visible light transmittance similar to pure MMA. TEM imagesshowed that the milled nanoparticles remained well dispersed in titania−PMMA nanocomposites, and theaddition of titania nanoparticles to PMMA increased the PMMA thermal stability. Spin-coated titania−PMMAfilms had higher refractive indices than pure PMMA films, with film of higher titania weight percent havinghigher refractive indices.
