摘要:本发明涉及一种具有至少1个丙烯酸功能基的末端基的高折射率单体,该单体设计满足折射率大于1.57的要求,所述高折射率单体单独或混合形式至少含有2种以上,以便控制折射率,粘度,硬度和黄变度的棱镜片成型用树脂组合物,利用由最佳配比制成的棱镜片成型用树脂组合物,实现高折射率和低粘度的固化前液体,形成透明且具有非常好抗黄变性的棱镜片.因此,本发明通过提供高折射率的棱镜片,减少了用于实现相同弯曲度所需的片数,有助于使产品更加轻薄,性能更好并降低成本,从而减少用于背光单元的led灯的数量,提供节能效果.

摘要:Preparation of capped metal oxide nanocrystals comprising a metal oxide shell that are photocatalytically and thermally stable and their dispersions in monomers, oligomers, and polymers, as well as the resulting formulations and nanocomposite films. These nanocrystals are highly monodisperse with nanocrystal size between 3-100 n. Resultant formulations incorporating these nanocrystals and a matrix material are highly stable and result in nanocomposites that have high refractive index, are highly transparent, have minimal to no change in absorption upon thermal or UV processing and are optically transparent in the visible wavelengths with very little or no scattering.
