Abstract
Disclosed are a poly dopamine film and a preparation method and application thereof. The polydopamine film is loaded with silver sulfadiazine, and the preparation method achieves in-situ synthesis of si sulfadiazine on a conventional polydopamine film by microwave irradiation. In the method, the sulfadiazine is not dissolved in conventional aqueous ammonia, which has the following advantages: firstly, preventing the polydopamine film from being corroded by the aqueous ammonia; secondly, protecting mucosa such as eyes and nasal cavities of workers from stimulation and corrosion of the aqueous ammonia; and thirdly, avoiding the environmental problem caused by pungent odor and fumes emitted from high-concentration aqueous ammonia. In the method, without using the catalyst trifluoromethanesulfonic acid or trifluoromethanesulfonic salt, not only is the loading of silver sulfadiazine increased, but also the safely performance can be further improved.
