以四异丙醇钛和甲氧基化聚二甲基硅氧烷为原料，采用共沉淀法合成了二氧化钛/聚二甲基硅氧烷杂化球形粒子。杂化粒子的折射率与二氧化钛含量呈线性关系。这些混合颗粒具有弹性性质。采用TEM、XRD、IR、UV-Vis等手段对产物的纳米结构进行了表征。光谱和HAADF-STEM。该杂化材料具有岛状纳米结构，由纳米尺寸范围内的二氧化钛和PDMS畴组成。
Spherical particles of titanium dioxide and poly(dimethylsiloxane) hybrid have been synthesized from titanium tetraisopropoxide and methoxy-functionalized poly(dimethylsiloxane) by a co-precipitation method. The refractive index of the hybrid particles exhibits a linear relationship with the titanium dioxide content. These hybrid particles have elastic properties. The nano structures of the products were characterized by TEM, XRD, IR, UV-Vis. spectroscopy and HAADF-STEM. The hybrids have an islet-like nano-structure, which consisted of titanium dioxide and PDMS domains in the nanometer size range.
