AI Technical Summary

Technical Problem

Existing ceramic tableware lacks antibacterial properties, especially with low antibacterial rates against Escherichia coli and Staphylococcus aureus. Furthermore, it lacks sufficient heat resistance and antibacterial durability, failing to meet the requirements of dishwashers, microwave ovens, and ovens.

Method used

Modified ceramic materials were prepared by combining microbead-type nano zinc oxide, zinc oxide nanowires, and powder-type nano zinc oxide in a specific mass ratio, and by modifying them with aminosilane coupling agent and polyethylene glycol trimethoxysilylpropyl ether, combined with a staged sintering process.

Benefits of technology

It improves the antibacterial and heat resistance of ceramic materials, has excellent and long-lasting antibacterial properties, is suitable for dishwashers, microwave ovens and ovens, and maintains excellent antibacterial properties after 125 wash cycles.
