Shape-tunable hollow silica nanomaterials, including hollow silica nano-spheres and nano-tadpoles, were synthesized with a one-step soft-templating method. A possible particle growth mechanism was proposed. Films were built from these shape-tunable hollow silica nanomaterials with refractive indices as low as 1.045, which is, to the best of our knowledge, the third-lowest value ever reported so far. For the first time, the refractive indices of films were tuned by changing the morphology of building blocks. These films are intrinsically hydrophobic. Moreover, the process used to prepare these nanomaterials without the need for expensive equipment or any post-treatment is well suited for industrial production on large surfaces.
采用一步软模板法合成了形状可调的中空二氧化硅纳米材料，包括中空二氧化硅纳米球和纳米蝌蚪。提出了一种可能的颗粒生长机制。用这些形状可调的中空二氧化硅纳米材料制备的薄膜的折射率低至1.045，据我们所知，这是迄今为止报道的第三低的值。首次通过改变构建块的形态来调节薄膜的折射率。这些薄膜本质上是疏水的。此外，制备这些纳米材料的过程无需昂贵设备或任何后处理，非常适合在大面积上进行工业生产。
