High refractive index organic–inorganic nanocomposites: design, synthesis and application

Superior thermal conductivity of transparent polymer nanocomposites with a crystallized alumina membrane

“…Lack of optical transmission in AAO membrane is due to surface light scattering and limitations for light diffusion through the thickness (60 &m) of membrane. In transparent organic-inorganic composites, filler size, composite surface roughness and refractive index (RI) difference [18] between inorganic phase and matrix might be responsible for their transparency. The light transmission percentages of annealed and unannealed composites are demonstrated in Figure 5a.…”

Highly transparent poly(2-ethyl-2-oxazoline)-TiO2nanocomposite coatings for the conservation of matte painted artworks

“…Some high refractive index polymer nanocomposites reported in literature were prepared with ZrO 2 (n=2.16 at 589 nm) 24 and ZnO (n=2.00 at 589 nm) 25 that, like TiO 2 , show also photocatalytic properties 26 . Moreover, TiO 2 is most often used as inorganic phase due to the higher refractive index and its easier preparation in both laboratory and industry 27 .…”

Design and process development of a photonic crystal polymer biosensor for point-of-care diagnostics

“…With the argon plasma treatment discussed above an approximately 1 µm thick polyimide film could also be spin-coated on top of Cytop. To increase the refractive index one can incorporate high refractive index nanoparticles, such as metal oxides, into the core layer [16], [17], [18], [19] . Since the thickness of the core layer has to be on a scale of hundreds of nanometres, the nanoparticles must be much smaller than these characteristic dimensions to obtain a uniform material with acceptable low scattering for the optical application.…”
