▎ 摘　　要

NOVELTY - A graphene-reinforced polyamide composite comprises a graphene incorporated in a polyamide resin by melt compounding graphene having ratio of carbon to oxygen of 85:15-99. The graphene is incorporated as a masterbatch with a compatibilizer as the matrix of the masterbatch. The graphene is chosen from graphene, multilayer graphene, graphene nanoplatelets, graphene oxide, reduced graphene oxide, doped graphene, and functionalized graphene. USE - Graphene-reinforced polyamide composite. Uses include but are not limited to automotive industry, aircraft, electronics, clothing, and machinery. ADVANTAGE - The graphene-reinforced polyamide composite has excellent mechanical and thermal properties, electrical properties, flame-retardance, tensile strength, and barrier properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for introduction of and evenly dispersing graphene nanoplatelets, which involves loading (12) a polyamide powder and fillers into an extruder, loading (14) exfoliated graphene platelets into a feeder, adjusting (16) a feeder rate for a desired dispersion weight percentage of the platelets in an end product masterbatch, adding (18) a compatibilizer to the polyamide and the fillers in the extruder, heating (20) the polyamide and fillers to form a molten thermoplastic, dispensing the platelets from the feeder into the molten thermoplastic to form a melted compound, where the melted compound exits the extruder in strands, and cooling (22) the strands and cutting the strands into pellets which forms the masterbatch. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart of introduction and evenly dispersing graphene. Loading polyamide and fillers into extruder (12) Loading exfoliated graphene platelets into feeder (14) Adjusting feeder rate for dispersion rate (16) Adding a compatibilizer and coupling agent to extruder (18) Heating polyamide and fillers to molten state and dispersing platelets from feeder (20) Cooling strands of melted compound (22)
