Claim 13:
14. A method comprising:
shearing a mixture comprising a polyamide, a carrier fluid that is immiscible with the polyamide, and nanoparticles at a temperature greater than a melting point or softening temperature of the polyamide and at a shear rate sufficiently high to disperse the polyamide in the carrier fluid;
cooling the mixture to below the melting point or softening temperature of the polyamide to form solidified particles comprising polyamide particles having a circularity of 0.90 or greater and that comprise the polyamide and the nanoparticles associated with an outer surface of the polyamide particles, wherein the polyamide particles have a D10 of about 0.5 μm to about 125 μm, a D50 of about 1 μm to about 200 μm, and a D90 of about 70 μm to about 300 μm, wherein D10<D50<D90; and
separating the solidified particles from the carrier fluid.
