Synthesis of silica nanoparticles having the controlled size and their application for the preparation of polymeric composites |
| 초록 |
Silica nanoparticles using in polymeric dental restorative composites were prepared by Stöber method, and then the effects of surface treatment of silica particles with 3-methacryloxypropyltrimethoxysilane (γ-MPS) on the dispersity of the silica particles in the organic matrix was investigated. Particles having various average size were prepared by using controled amounts of tetraethylorthosilicate (TEOS), water, and catalyst and by changing solvent used for reaction. Hydrophobic silica nanoparticles was prepared by reacting hydrophilic nanoparticles with γ-MPS to improve interfacial properties with organic matrix. The dispersity of the silica particles in the organic matrix was improved when the surface treated silica particles were used for preparing the polymeric dental restorative composites. |
