摘要：Antimicrobial polyamide (PA) received much attention for the demand of packaging and biomedical fields. In this paper, an antimicrobial PA6 membrane was prepared via a surface chemical reaction. A highly effective antibacterial component (PHMG-E) with terminal epoxy group was firstly synthesized via a reaction between polyhexamethylene guanidine hydrochloride (PHMG) and ethylene glycol diglycidyl ether (EGDE). Then, PHMG-E was bonded on the surface of PA6 membrane with secondary amine reduced by borane-tetrahydrofuran (BH3-THF). The antimicrobial rates of surface-modified PA6 membrane (PA6-PHMG) against Escherichia coli and Staphylococcus aureus were both higher than 99.99%, and the PHMG was non-leaching due to the chemical bonding. The hydrophilicity of antibacterial PA6 membrane was also significantly improved and the mechanical performance became better.
