Tunable High Refractive Index Polymer Hybrid and Polymer–Inorganic Nanocomposite Coatings

“…The refractive index reported here is also higher than for other nanocomposite coatings where nanoparticles were incorporated into a host polymer containing bromine atoms and aromatic rings in order to obtain high refractive index films. 66 , 67 Furthermore, the refractive index attained in the current investigation is larger than earlier values for low loading of polymer–inorganic nanocomposite coatings (≤10 wt % inorganic material): n = 1.73 (8 wt % TiO 2 ), 54 n = 1.81 (8 wt % HfO 2 ), 68 and n = 1.833 (10 wt % carbon black). 33 Synthesis of coatings containing titania where the refractive index was slightly higher than the 1.936 value reported in the present study includes wet preparation by nanoparticle dispersion into polymers 32 and the sol–gel method.…”

“…The refractive index obtained for the 3:2 v/v 4-bromostyrene/toluene + 8% w/v titania ASPD nanocomposite coating ( n 635 nm = 1.936) exceeds a previous report where titania was added prior to UV-induced liquid-phase monomer polymerization ( n = 1.861). The refractive index reported here is also higher than for other nanocomposite coatings where nanoparticles were incorporated into a host polymer containing bromine atoms and aromatic rings in order to obtain high refractive index films. , Furthermore, the refractive index attained in the current investigation is larger than earlier values for low loading of polymer–inorganic nanocomposite coatings (≤10 wt % inorganic material): n = 1.73 (8 wt % TiO 2 ), n = 1.81 (8 wt % HfO 2 ), and n = 1.833 (10 wt % carbon black) . Synthesis of coatings containing titania where the refractive index was slightly higher than the 1.936 value reported in the present study includes wet preparation by nanoparticle dispersion into polymers and the sol–gel method. − , However, in all of these cases, the titania loading was greater (16–93.4 wt %) than that of employed here, which often results in higher optical loss and reduces the processability of the organic matrix .…”

Synthesis and Properties of High‐Refractive‐Index Iodine‐Containing Polyacrylates

“…Polymers with high values of refractive index (n D ), particularly n D > 1.60, have a wide range of applications, including antireflection coatings, [1,2] optical lenses, [3] light-emitting diodes, [4][5][6][7] 3D printing materials, [8,9] and nanoimprinting materials, [10][11][12][13][14] and there is great interest in the development of higherrefractive-index polymers.…”

Zirconium dioxide@phosphazene for enhancing mechanical property, flame retardancy, and thermal property of polythiourethane composites

“…[18][19][20][21][22] Several strategies for introducing ZrO 2 into the polymer matrix have emerged; these include physical addition and in-situ polymerization. 19,[23][24][25][26] Compared with the latter, the former has the advantages of economy, simple operation and mild conditions, and has been widely adopted by numerous researchers. However, due to the deformation incompatibility and the shortcomings of ZrO 2 being easy to agglomerate, severe stress concentration and poor dispersibility could be easily induced in the polymer network structure, resulting in the degradation of polymer performance.…”
