The invention discloses a polydopamine film and a preparation method and application thereof. The poly-dopamine film is loaded with silver sulfadiazine, and the preparation method realizes the in-situ synthesis of the silver sulfadiazine on the conventional poly-dopamine film through microwave irradiation. In the method, the sulfadiazine is not dissolved by the traditional ammonia water, and the method has the following advantages: firstly, the corrosion effect of ammonia water on the polydopamine film can be avoided; secondly, the irritation and corrosion of ammonia water to mucous membranes such as eyes, nasal cavities and the like of workers can be avoided; thirdly, the environmental problem caused by the smoke with pungent smell volatilized by the high-concentration ammonia water can be avoided. In the method, the triflic acid or the triflate which is not used as a catalyst can be used for improving the loading capacity of the silver sulfadiazine and further improving the safety performance. |
