Embodiment 1
[0026] Polystyrene microspheres, polymethyl methacrylate microspheres and titanium dioxide microspheres were dispersed in water to prepare a colloidal emulsion with a mass fraction of 6%, and the mass ratio of the three was 2:2:1.
[0027] Cut a certain amount of cocoons into about 1cm 2 The fragments were added to the boiling 1wt% NaOH aqueous solution, and after boiling for 30 minutes, the degummed silk was rinsed with deionized water until the sericin was completely removed. After the degumming is complete, the silk fibroin is dried in an oven at 40°C. Weigh a certain amount of degummed silk, add it at a bath ratio of 1:10 and completely soak it in a container filled with 5M LiBr solution, and then keep the container at 60°C for one hour. Then put the solution into a dialysis bag with a molecular weight cut-off of 7000 and dialyze for three days to obtain the silk protein aqueous solution. Adding carboxymethyl cellulose and lanthanum chloride into the silk protein aqueous...

Embodiment 3
[0034] Polystyrene microspheres, polymethyl methacrylate microspheres and titanium dioxide microspheres were dispersed in water to prepare a colloidal emulsion with a mass fraction of 15%, and the mass ratio of the three was 2:1:1.
[0035] Cut a certain amount of cocoons into about 1cm 2The fragments were added to the boiling 1wt% NaOH aqueous solution, and after boiling for 30 minutes, the degummed silk was rinsed with deionized water until the sericin was completely removed. After the degumming is complete, the silk fibroin is dried in an oven at 40°C. Weigh a certain amount of degummed silk, add it at a bath ratio of 1:10 and completely soak it in a container filled with 5M LiBr solution, and then keep the container at 60°C for one hour. Then put the solution into a dialysis bag with a molecular weight cut-off of 7000 and dialyze for three days to obtain the silk protein aqueous solution. Adding methyl cellulose and cerium chloride into the silk protein aqueous solution,...
