| titleOfInvention | An ionic liquid-modified chitosan derivative and its preparation method and application |
| abstract | The invention discloses an ionic liquid-modified chitosan derivative and a preparation method and application thereof, including the preparation of phenolic modified chitosan, the preparation of zinc-coordinated ionic liquid, and the preparation of ionic liquid-modified chitosan derivative 3 steps, the present invention enhances the water solubility and biological activity of chitosan by phenolic modification of chitosan, and the phenols have oxidative properties and have a certain bactericidal effect, which improves the antibacterial effect of chitosan. Then, the zinc-coordinated ionic liquid is grafted on chitosan through the Mannich reaction, so that the chitosan derivative material has good mechanical properties, and the ionic liquid has a large specific surface area, which can adsorb bacteria through electrostatic force. , and then use active groups and zinc ions to achieve the purpose of sterilization. In addition, the long alkyl chain in the ionic liquid easily enters the hydrophobic area of the bacterial cell membrane, changing the permeability of the cell membrane and cell osmotic pressure, thereby killing bacteria and further improving The antibacterial properties of chitosan. |
