Embodiment 1
[0030] An organic / inorganic composite core-shell structure type bactericidal material, the preparation method of which is as follows:
[0031] (1) Weigh 100g of polyvinylpyrrolidone, add it to the reaction vessel, add 750mL of ethylene glycol, put it in an oil bath at 85°C and stir it mechanically until it is completely dissolved, add 4g of AgNO 3 Solid, stirred until completely dissolved, then heated up to 105°C, reacted for 2 hours, naturally cooled to room temperature, added acetone, stirred to disperse, and centrifuged at high speed to obtain nano-silver glue;
[0032] (2) Weigh 300 mg of nano-silver colloid and ultrasonically disperse it in 100 mL of toluene, add it to the reaction vessel, stir and disperse, slowly add 3 mL of tetrabutyl titanate and 3 mL of triethylamine with a syringe, stir at room temperature for 24 hours, and then centrifuge at high speed , to collect the resulting particles;
[0033] (3) drying the microparticles obtained in step (2) after washing w...
Embodiment 2
[0040] An organic / inorganic composite core-shell structure type bactericidal material, the preparation method of which is as follows:
[0041] (1) Weigh 150g of polyvinylpyrrolidone, add it to the reaction vessel, add 1000mL of ethylene glycol, stir in an oil bath at 85°C until completely dissolved, add 6g of AgNO 3 Solid, stirred until completely dissolved, then heated up to 115°C, reacted for 3 hours, naturally cooled to room temperature, added acetone, stirred to disperse, and separated by high-speed centrifugation to obtain nano-silver glue;
[0042] (2) Weigh 400 mg of nano-silver colloid and ultrasonically disperse it in 150 mL of toluene, add it to the reaction vessel, stir and disperse, slowly add 5 mL of tetrabutyl titanate and 5 mL of triethylamine with a syringe, stir at room temperature for 24 hours, and then centrifuge at high speed , to collect the resulting particles;
[0043] (3) drying the microparticles obtained in step (2) after washing with absolute ethanol ...
