Metal Oxide Particles with Uniform Multilayer Polymer Coatings |
| 摘要 |
The present invention is a multilayered composite comprising porous metal oxide particles that are covalently bonded by way of inorganic ether groups to one or more sites of a first polyhydroxyl-functionalized polymer. This first polymer is in turn covalently bonded by way of inorganic ether groups to one or more sites of a second polyhydroxyl-functionalized polymer. The multilayered composites can be prepared by contacting porous inorganic-oxide particles with a sufficient amount of OH-reactive crosslinking agent to form metal oxide particles imbibed with the crosslinking agent, and then contacting the inorganic-oxide particles with a solution of polyhydroxyl-functionalized polymer under reactive conditions. |

1. A multilayered composite comprising porous metal oxide particles that are covalently bonded, by way of inorganic ether groups to one or more sites of a first polyhydroxyl-functionalized polymer, which is covalently bonded by way of inorganic ether groups to one or more sites of a second polyhydroxyl-functionalized polymer. |
