Synthesis and Application of Quaternary Ammonium-Functionalized Hyperbranched Polyester Antibacterial Agent

Abstract:

In the presence of alkaline catalyst sodium hydroxide, the intermediate of hyperbranched polyester (H20Cl) was prepared by the modification of hyperbranched polyester Boltorn H20 with epichlorohydrin. Then a new kind of quaternary ammonium functionalized hyperbranched polyester antibacterial agent (H20C16N) was synthesized by the reaction of H20Cl and hexadecyldimethylamine. The structures characterizations of H20C16N were characterized by ¹H NMR. The application of H20C16N used as antibacterial agent of silk fabric was studied. The antibacterial ratio was 99.06% against escherichia coli and 98.24% against staphylococcus aureus.The excellent antibacterial properties of treated silk fabric were provided.
