利用Stber方法合成了SiO_2纳米粒子,并对其进行了改性,得到了分散性好的SiO_2纳米粒子。通过粒度分析仪及透射电镜研究表明,SiO_2纳米粒子的平均粒径在100nm左右。并阐述了改性剂对SiO_2的改性机理。
SiO 2 nanoparticles were synthesized by Stber method and modified to obtain SiO 2 nanoparticles with good dispersibility. The particle size analyzer and transmission electron microscopy showed that the average size of SiO 2 nanoparticles was about 100 nm. The modification mechanism of modifier on SiO 2 is also described.
