preparation of inorganic-organic hybrid microparticles by droplet based microfluidic system |
| 초록 |
The synthesis of organic-inorganic hybrid particles with highly controlled particle sizes in the micrometer range is a major challenge in many areas of research. In this work, the droplet-based microfluidic method combined with in situ photopolymerization produces highly monodisperse silanol groups functionalized organic microparticles in a simple manner, and the silica nanoparticles gradually grow on the surface of the microparticles prepared via hydrolysis and condensation of tetraethoxysilane (TEOS) in a basic ammonium hydroxide medium without additional surface treatment. This approach leads to a reduction in the number of processes and allows drastically improved size uniformity compared to conventional methods. As a result, Organic core of hybrid particles is completely covered with the silica nanoparticles of approximately 60nm. |
