PROCESS FOR PREPARING RECYCLABLE TEMPLATE HOLLOW PARTICLES USING WATER-BASED SILICA PRECURSORS |
| 摘要 |
The disclosure provides a process for making hollow inorganic particles comprising: providing a recyclable template particle in an aqueous dispersion, wherein the recyclable template particle is prepared from an organic monomer; coating the recyclable template particle with a water-based silica precursor; maintaining the pH at about 2 to about 10 to form core/shell particles comprising a silica treatment on the recyclable template particle; removing the core/shell particles; and removing the recyclable template particle from the core/shell particles to form a hollow silica particle. |

1. A process for making hollow inorganic particles comprising:
(a) providing a recyclable template particle in an aqueous dispersion, wherein the recyclable template particle is prepared from an organic monomer; (b) coating the recyclable template particle with a water-based silica precursor; (c) maintaining the pH at about 2 to about 10 to form core/shell particles comprising a silica treatment on the recyclable template particle; (d) removing the core/shell particles; and (e) removing the recyclable template particle from the core/shell particles to form a hollow silica particle. |
