▎ 摘　　要

NOVELTY - Method for selective laser sintering involves depositing carbon nanomaterial-graft-polyamide (CNM-g-polyamide) particles optionally in combination with other thermoplastic polymer particles onto a surface, where the CNM-g-polyamide particles comprise a polyamide grafted to a carbon nanomaterial (CNM), and exposing at least a portion of the CNM-g-polyamide particles to laser to fuse the polymer particles and form a consolidated component by selective laser sintering. USE - Method for selective laser sintering for three-dimensional article. Uses include but are not limited to shoe soles, furniture component, decorative home goods, plastic gears, cable ties, jewelry, sculpture, orthopedic implants, dentistry, sporting goods, etc. ADVANTAGE - The method provides highly spherical CNM-g-polyamide particles to improve dispersion capabilities with carbon nanomaterial. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing CNM-g-polyamide particles, which involves: (a) mixing a mixture (112) of CNM-g-polyamide (102), a carrier fluid (104) which is immiscible with the polyamide of the CNM-g-polyamide, optional thermoplastic polymer (108) not grafted to CNM, and optional emulsion stabilizer (106) at temperature greater than melting point or softening temperature of the polyamide of the CNM-g-polyamide and the thermoplastic polymer, when included, and at a shear rate sufficiently high to disperse the CNM-g-polyamide in the carrier fluid; (b) cooling the mixture to below melting point or softening temperature to form CNM-g-polyamide particles; and (c) separating the CNM-g-polyamide particles from the carrier fluid. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of the method for preparing CNM-g-polyamide particles. 102CNM-g-polyamide 104Carrier fluid 106Optional emulsion stabilizer 108Optional thermoplastic polymer not grafted to CNM 112Mixture
