摘要：有高折射的索引(RI ) 的碳黑人(CB )/polymer composites 被制作从 poly (乙烯基白酒)(PVA ) 并且 covalently 由简单酯化作用反应的 functionalized nano-CB (PVA-es-CB ) 。传播电子显微镜学证明有比 100 nm 小的一种尺寸的 PVA-es-CB nanoparticles 的一致总数在 nanocomposite 电影形成了。Ellipsometric 大小显示 PVA-es-CB/PVA 合成电影在 1.5201.598 线性地与 PVA-es-CB 体积内容增加了的范围有 RI。理论方程基于 Lorentz-Lorenz 理论提供了折射索引的相当靠近的评价给试验性地观察的价值。混合电影也揭示了相对好的表面 planarity，热稳定性和光透明性。
Carbon black （CB）/polymer composites with high refractive index （RI） were fabricated from poly（vinyl alcohol） （PVA） and covalently functionalized nano-CB （PVA-es-CB） by simple esterification reaction. Transmission electron microscopy showed that tmifonn aggregates of PVA-es-CB nanoparticles with a size smaller than I00 nm formed in the nanocomposite films. Ellipsometric measurements indicated that the PVA-es-CB/PVA composite films had a RI in the range 1.520-1.598 linearly increased with the PVA-es-CB volume content. Theoretical equation based on Lorentz-Lorenz theory provided reasonably close estimation of the refractive indices to the experimentally observed values. The hybrid films also revealed relatively good surface planarity, thermal stability and optical transparency.
