The silica/polydimethylsilane (PDMS) hybrid nanoparticles were successfully synthesized by a novel solvent adjustment route. The as-prepared hybrid nanoparticles were characterized by transmission electron microscopy, UV-vis spectra, and IR spectra. The possible mechanism for the formation of silica/PDMS nanoparticles was discussed. The adjustment of solvents is a very important factor since it could tune the surface ligands and improve the coordination ability. On the other hand, it could also tune the interaction between precursors, intermediate or the target hybrid materials and guarantee the monodispersion of prepared nanoparticles. With the merits of PDMS and silica, the as-prepared SiO2-PDMS hybrid nanoparticles have a good application in hard coating material.
通过一种新型的溶剂调节路线成功合成了二氧化硅/聚二甲基硅氧烷（PDMS）杂化纳米粒子。通过透射电子显微镜、紫外可见光谱和红外光谱对所制备的杂化纳米粒子进行了表征。讨论了二氧化硅/PDMS纳米粒子形成的可能机理。溶剂的调节是一个非常重要的因素，因为它可以调节表面配体并提高配位能力。另一方面，它还可以调节前驱体、中间体或目标杂化材料之间的相互作用，并保证所制备纳米粒子的单分散性。由于PDMS和二氧化硅的优点，所制备的SiO2-PDMS杂化纳米粒子在硬涂层材料中有良好的应用。
