Claim 13:
14. A method comprising:
combining a polyurethane polymer and nanoparticles with a carrier fluid at a heating temperature at or above a melting point or a softening temperature of the polyurethane polymer;
wherein the polyurethane polymer and the carrier fluid are substantially immiscible at the heating temperature;

applying sufficient shear to disperse the polyurethane polymer as liquefied droplets in the presence of the nanoparticles in the carrier fluid at the heating temperature;
after liquefied droplets have formed, cooling the carrier fluid to at least a temperature at which elastomeric particulates in a solidified state form, the elastomeric particulates comprising the polyurethane polymer and a plurality of the nanoparticles, the polyurethane polymer defining a core and an outer surface of the elastomeric particulates and the plurality of the nanoparticles being associated with the outer surface;
wherein the elastomeric particulates have a D50 ranging from about 1 μm to about 1,000 μm; and

separating the elastomeric particulates from the carrier fluid.
