Deskripsi
Cellulose hydrogels with quaternary ammonium (QA) groups were prepared via the etherification and cross-linking reaction. The structure of the functional hydrogels with QA groups was confirmed with FT-IR. Differential scanning calorimeter (DSC) analysis indicated that there was a large amount of free water in the hydrogels. The hydrogels showed salt-sensitivity behavior, and they also exhibited a strong antibacterial activity toward Escherichia coli.
