Surface fluid-swellable chitosan fiber as the wound dressing material

The objective of this study was to develop a novel surface fluid-swellable chitosan (SFSC) fiber for potential wound dressing. The SFSC fiber was successfully prepared by surface modification of chitosan fiber with succinic anhydride, which was characterized by FTIR and solid-state 13C NMR. The SFSC fiber exhibited better water absorption capacity (approx. 2980%) and stronger antibacterial activities (both above 90%) against Escherichia coli (E....
