Abstract
Compositions and methods for preparing at least partially hollow nanoparticles having an outer shell comprising a one or more molecules and/or residues derived from a metal soap, where the nanoparticles each comprise a continuous inner void space that averages at least 10 percent of the volume of each of the nanoparticles. Such at least partially hollow nanoparticles can be employed in a variety of applications including, but not limited to, tire manufacturing.
Claims46
A composition comprising:
- an at least partially hollow nanoparticle having an outer shell comprising one or more molecules and/or residues derived from a metal soap, the metal soap including a metal and a carboxylate group, the outer shell comprising the metal and the carboxylate group;
- wherein said at least partially hollow nanoparticle comprises at least one continuous inner void space that constitutes at least 10 percent of the volume of said nanoparticle;
- wherein the metal of said metal soap comprises a transition metal, a post-transition metal, a metalloid, a lanthanoid, and/or an actinoid;
- wherein the metal of said metal soap has a valence of at least 3.
