System and method of preparing a reinforced polymer by supercritical fluid treatment
First Claim
1. A method of generating a reinforced polymer, the method comprising:
- providing particles of layered silicate and a supercritical fluid;
mixing the layered silicate particles with a polymer to form a treatable silicate-polymer mixture;
contacting the treatable mixture with the supercritical fluid to exfoliate the silicate so that the silicate particles disperse within the polymer; and
depressurizing the contacted mixture to further exfoliate the silicate particles so that the particles are substantially dispersed within the polymer to define a reinforced polymer.

Abstract
The present invention involves a method of preparing a reinforced polymer providing improved mechanical properties. The method includes providing particles of the layered silicate and a supercritical fluid. The method further includes mixing the layered silicate with a polymer to form a treatable silicate-polymer mixture and contacting the treatable mixture with the supercritical fluid to exfoliate the silicate particles so that the particles disperse within the polymer. The method further includes depressurizing the contacted mixture to exfoliate the layered silicate so that the layers are substantially dispersed within the polymer to define a reinforced polymer.
