Abstract
Composite particles of a metal oxide particle within a crosslinked, cored dendrimer are described. Additionally, methods of making the composite particles and compositions that contain the composite particles are described.
Claims9
A composition comprising a composite particle, the composite particle comprising
- a cored dendrimer comprising crosslinked dendrons surrounding a central interior region that is free of organic material, and
- a metal oxide particle within the cored dendrimer, wherein the metal oxide particle has a size that is larger than the central region of the cored dendrimer that is free of organic material.
A composition comprising a composite particle, the composite particle comprising
- a cored dendrimer comprising crosslinked dendrons surrounding a central interior region that is free of organic material;
- a metal oxide particle within the cored dendrimer;
- and
- an organic matrix, wherein the composite particle is dispersed or suspended in the organic matrix.
