摘　　要：利用Stber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。SiO2 nano-particles were synthesized by means of stoeber method, and the surfaces of the nano-particles were modified. The average size of the SiO2 nano particles is about 100nm which is analysized by Zepals and TEM. The mechanism of modifier that modified SiO2 nano-particles was expatiated.
