| Abstract: | Chitosan is a natural nontoxic biopolymer used widely in various fields due to the antimicrobial activities. In this study,
the properties of polyester fabrics grafted with chitosan oligomers/polymers after being activated by atmospheric pressure
plasmas were evaluated. The antibacterial effect was most evident when the surface of fabrics was activated by atmospheric
pressure plasma for 60 to 120 seconds and grafted with chitosan oligomers. The modified fabrics also exhibited good biocompatibility.
This process can be applied to a large area and used to produce antibacterial polymer fibers. |
