| titleOfInvention | Method for preparing antibacterial film of quaternarized chitosan iodine complex |
| abstract | The invention relates to a method for preparing an antibacterial film of a quaternarized chitosan iodine complex. The method comprises the following steps: inserting quaternary ammonium salt on the hydroxyl group or amino group of a chitosan structure unit to prepare a quaternarized chitosan derivative; soaking a blend film of the quaternarized chitosan derivative and gelatin or poval into a simple substance iodine solution for 4-6 hours to obtain the antibacterial film of the quaternarized chitosan/gelatin or poval iodine complex, or directly preparing a quaternary ammonium salt chitosan iodine complex from the quaternarized chitosan derivative and simple substance iodine, and then mixing the quaternary ammonium salt chitosan iodine complex with gelatin or poval to prepare the blend antibacterial film containing iodine. By using the method, the water solubility and the biological activity of chitosan can be improved; simple substance iodine is stabilized and complexed by utilizing the affinity of a quaternary ammonium salt group and an iodine molecule; according to the different positions of a human body, the prepared antibacterial film can be compounded with other materials; a chitosan base has hemostasis, antiphlogosis and tissue repair functions on human body wound, can reduce the stimulation of iodine on the wound and controls the release of iodine, and the double effects of the chitosan base and iodine provide an ideal curing environment for a wound surface. |
