摘要

通过在原材料中添加透明釉料，制备了具有高孔隙率和高机械性能的多孔 Al2O3 陶瓷。通过化学还原法将 AgNPs 涂覆在多孔 Al2O3 陶瓷上。包覆了 AgNPs 的多孔 Al2O3 陶瓷具有很高的抗菌性能，对金黄色葡萄球菌的抗菌率高达 98.8%。经过 30 次浸泡后，抗菌率仍能达到 74.7%，显示出优异的循环性能，可广泛应用于游泳池、鱼缸、冲厕池等日常消毒场合。

Preparation and antibacterial properties of porous alumina ceramics coated with silver nanoparticles

Porous Al₂O₃ ceramics with high porosity and high mechanical properties were prepared by adding transparent glaze to the raw material. AgNPs were coated on porous Al₂O₃ ceramics by a chemical reduction method. The porous Al₂O₃ ceramics coated with AgNPs had high antibacterial properties, and the antibacterial rate against S. aureus was up to 98.8 %. After 30 times soaking, the antibacterial rate still reached 74.7 %, showing excellent cycling performance, and can be widely used in swimming pools, fish tanks, flushing toilet tanks and other daily disinfection occasions.
