The present invention discloses a preparation method for transition metal and rare earth complex-modified nylon 66. Prepared dezipped carbon nanotubes are mixed with transition metal salts to obtain transition metal-anchored dezipped carbon nanotube nanofillers. The transition metal-anchored dezipped carbon nanotube nanofiller is uniformly mixed with a solution of rare earth ion organic ligands. After stirring, washing, vacuum filtration, drying, and collection, a fluorescent hybrid luminescent material is obtained. The fluorescent hybrid luminescent material is uniformly blended with nylon 66 pellets via mechanical stirring. The homogeneous mixture is then fed at a constant rate into a twin-screw extruder for melt heating and extruded through a fine-diameter die, yielding nylon 66 masterbatch modified with transition metal-rare earth complexes. The prepared composite material was tested for mechanical properties using a universal testing machine, showing a tensile strength increase of approximately 75% compared to pure nylon 66. Fluorescence performance was evaluated via UV spectrophotometry, with fluorescence intensity reaching 3.0×10⁵ candela.
