Preparation for in-situ compounding simple-substance nano silvery bacteria cellulose membrane

The invention provides a preparation for the in-situ compounding simple-substance nano silvery bacteria cellulose membrane, and relates to the biological medical material field, characterized in that the bacteria cellulose membrane has special three-dimensional nano network structure, the silver-ammonia solution reacts with the chemical agent containing aldehyde group to generate silver simple-substance nano particle in situ in the network structure. In addition, in the invention, the special drying method is adopted to improve the defect of big fragility of the prepared silver-contained nano bacteria cellulose dry membrane. The bacteria cellulose membrane containing simple-substance nano silver particle provided by the invention has excellent antibacterial performance and simple preparation technique, and can be widely used in the biological medical field such as large-area wound dressing, bundling belt and the like, also can be used in the industry field such as the preparation of nano silver particle and silver catalyst, and the like.
