NOVELTY - Antibacterial and antistatic APET composite material comprises 78-92 pts. wt. APET, 2-5 pts. wt. compatibilizer, 3-8 pts. wt. toughening agent, 3-8 pts. wt. antibacterial and antistatic agent, 0.1-0.5 pts. wt. antioxidant, 0.1-0.5 pts. wt. lubricant. USE - Antibacterial and antistatic APET composite material. ADVANTAGE - The antibacterial and antistatic APET composite material effectively improves the antibacterial and antistatic ability of APET by adding hyperbranched polyethyleneimine modified graphene oxide (BPEIMGO) to load nano silver. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing an antibacterial and antistatic APET composite material, which involves: (A) preparing enough hyperbranched polyethyleneimine modified graphene oxide to support nano silver; (B) taking 78-92 pts. wt. APET, 2-5 pts. wt. compatibilizer, 3-8 pts. wt. toughening agent, 3-8 pts. wt. antibacterial and antistatic agent, 0.1-0.5 pts. wt. antioxidant, and 0.1-0.5 pts. wt. lubricant; and (C) pelletizing mixture by a twin-screw extruder to obtain an antibacterial and antistatic APET composite material.
