The present invention discloses a method for preparing PBAT-FITC material, comprising the following steps: taking unmodified ordinary PBAT granules, mixing them in a high mixer for at least 5 minutes, uniformly spraying sodium hydroxide solution during the mixing process, so that sodium hydroxide is uniformly mixed on the surface of PBAT granules; The material obtained from the steps is melted and extruded through a parallel twin-screw extruder, and then granulated, followed by drying to obtain short chain PBAT particles; Short chain PBAT particles were uniformly mixed with FITC in the dark and placed in a torque rheometer for reaction before being removed to obtain PBAT-FITC graft copolymer; Wash the PBAT-FITC graft copolymer until the fluorescence in the cleaning solution disappears, and then dry the cleaned sample to obtain PBAT-FITC material.
The present invention enables the simple and rapid preparation of PBAT-FITC materials with high grafting efficiency and high fluorescence intensity.
