Abstract
A method for producing polyamide particles may include: mixing 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; and separating the solidified particles from the carrier fluid.
