| titleOfInvention | A kind of preparation method of nano-silica core-shell structure particles |
| abstract | The present application discloses a preparation method of nano-silica core-shell structure particles. The silane coupling agent is hydrolyzed under the condition of an acidic catalyst, then added to orthosilicic acid, and then the mixed solution is mixed with silica sol and an alkaline catalyst. Mixing, aging, and finally obtaining nano-silica core-shell structure particles. The method only performs core-shell growth on nano-silica particles, and performs hybrid coating on the particles without introducing other elements. The experimental steps are simple and can cover most silane coupling agents. The nano-silica core-shell structure particles prepared by the method can be widely used in high-tech fields such as large health and semiconductors as organosilicon/inorganic silicon composite core-shell nanomaterials. |
