- Abstract
- In this study, the Janus silica particles were prepared by grafting reaction based on the sol-gel method. Before the surface modification reaction, the silica particles were trapped in the PS layer and some fraction of their surface were only reacted with APTES. XPS analysis confirmed that the nitrogen compounds were introduced on the surface of the Janus particles, and the curve fitting of nitrogen confirmed that the compounds were the amine groups. From the result of SEM analysis, there were no differences in the size and the surface morphology and no formation of the APTES clusters. Based on these results, it was confirmed that the Janus silica particles were prepared using PS trapping layer.
