Embodiment 1
[0038] The preparation method is as follows:
[0039]The first step, take by weighing sodium alginate 5Kg and carboxymethylated chitin 50Kg respectively, standby;
[0040] Put sodium alginate in a container, add distilled water to prepare 500Kg of a sodium alginate aqueous solution with a concentration of 1% by mass; place carboxymethylated chitin in a container, add distilled water to prepare a concentration of 10% by mass modified chitin aqueous solution 500Kg;
[0041] Then, the above-mentioned modified chitin aqueous solution was added to the above-mentioned sodium alginate aqueous solution while stirring; and the stirring was continued for 60 minutes, so that the fit reaction between the two was complete, and after concentration, the hygroscopic supramolecular GCP was obtained;
[0042] In the second step, press Ag + The mass ratio to GCP is 3:1000, add silver nitrate solution to the hygroscopic supramolecular GCP, and stir for 30-60 minutes to make the two undergo a co...
