Abstract: The present application discloses an antimicrobial nylon material, along with its preparation method and application. The present application relates to the technical field of antimicrobial polymer materials and addresses the limitations of existing antimicrobial nylon 6, particularly its insufficient antimicrobial efficacy and challenges in scalability for industrial production. In the present application, a seven-membered cyclic lysine-derived monomer is copolymerized with a lactam via hydrolytic copolymerization using water as an initiator, yielding a copolyamide. The resulting copolyamide is then subjected to a protonation reaction through heating and stirring in an acidic solution, followed by purification to obtain the final antimicrobial nylon material. The seven-membered cyclic lysine-derived monomer may be an unprotected cyclic lysine monomer, a mono-protected cyclic lysine monomer, or a salt form cyclic lysine monomer.
