Functional monomer N-methylolacrylamide was grafted onto microcrystalline cellulose to prepare the intermediates MCC-g-PHAM by atom transfer radical polymerization (ATRP) in ionic liquid 1-allyl-3-methyl-imidazole chloride. Halogenation was used to convert N-H in graft copolymer into N-Cl bond to obtain antibacterial copolymer
and its antibacterial properties were studied. The obtained polymer structure
surface morphology and antibacterial properties were characterized by FT-IR
1H NMR
SEM and antibacterial test. The result showed that the cellulose graft copolymer has been successfully synthesized and the surface after grafting became noticeably rougher. Therefore
the contact between the material and the bacteria is facilitated and the antibacterial performance is fully exerted. The material exhibits perfect antibacterial performance against Staphylococcus aureus and Escherichia coli. Thus the obtained material presents a better application prospect on the antibacterial field.
