双功能壳聚糖衍生物的合成与抗菌性研究

he modification of chitosan was studied by drawing anti-bacterial functional groups into hydroxyl and amino groups. A series of a single anti-bacterial function group chitosan derivatives and three kinds of chitosan derivatives with dual anti-bacterial function groups were synthesised The modified chitosan not only increased the water-solublility, but also enhanced its antibacterial properties. Synthetic derivatives of chitosan have been finished onto cotton fabric to endow it with anti-bacterial properties.
