Embodiment 1
[0030] (1) Mix styrene and α-methacrylic acid with deionized water, use potassium persulfate as an initiator, stir at a constant temperature of 60-80°C, and polymerize for 6-10 hours. After the reaction is completed, centrifuge and wash, and finally dissolve in absolute ethanol to obtain a polystyrene (PS) suspension;
[0031] (2) preparing a bismuth nitrate solution with a mass percentage of 60-80%, adding a certain amount of dispersant during the stirring process, and stirring until dissolved to obtain liquid A;
[0032] (3) Slowly add the sodium metasilicate solution (the molar ratio of silicon ions to bismuth ions is 1:1-1:1.5) with a mass percentage of 20-50% into the liquid A, and continue to stir. After mixing evenly, add 12mL of PS suspension to obtain the precursor solution;
[0033] (4) keeping the precursor solution in a stainless steel airtight autoclave with a polytetrafluoroethylene liner at 150-250°C for 8-15 hours, and then naturally cooling to room temperatur...
Embodiment 2
[0036] (1) Mix styrene and α-methacrylic acid with deionized water, use potassium persulfate as an initiator, stir at a constant temperature of 60-80°C, and polymerize for 6-10 hours. After the reaction is completed, centrifuge and wash, and finally dissolve in absolute ethanol to obtain a polystyrene (PS) suspension;
[0037] (2) preparation mass percentage is the bismuth nitrate solution of 60~80%, adds a certain amount of dispersant (comprising citric acid, EG, polyethylene glycol 400, polyethylene glycol 6000 etc., the concentration of each dispersant Controlled at 0.3~1.2mol / L), stir until dissolved to obtain liquid A;
[0038] (3) Slowly add the sodium metasilicate solution (the molar ratio of silicon ions to bismuth ions is 1:1-1:1.5) with a mass percentage of 20-50% into the liquid A, and continue to stir. After mixing evenly, add 16mL of PS suspension to obtain the precursor solution;
[0039] (4) keeping the precursor solution in a stainless steel airtight autoclav...
