二氧化硅微球颗粒在无水和水相介质中都极易发生自组装现象,进而严重影响该颗粒的特性研究。为了更好地使用和研究二氧化硅微球颗粒,需要进行解团聚工艺研究。实验研究了不同尺度的颗粒的团聚特性和现象,提出了一种工艺,该工艺方法可以很好地实现大团聚的二氧化硅微球颗粒的解团聚。经过尼康显微镜观察,显示该工艺不仅很好地完成了二氧化硅微球的解团聚,而且提高了颗粒的分散性和稳定性。

Silica microspheres in the anhydrous and aqueous media are prone to self-assembly, which would seriously affect the properties of the particle research. In order to study the use of silica microspheres and particles, the research on the de-aggregation of silica microspheres needs to be carried out. We propose a method which is able to achieve the reunion of silica microspheres and particles. We experimentally study the characteristics of different scales reunion particles and phenomena. By using a Nikon microscope, it shows that silica microspheres de-aggregation can be well done, and the dispersion and stability of the particles can be improved.
