Antimicrobial glass and glass-like products and method of preparing same

公开了一种玻璃或类似玻璃的基质，其至少一个表面区域具有能接触杀灭、非沥滤的抗微生物有效量的金属离子，该基质的颜色在CIE国际色标中为b#+[*]≤+6。所述抗微生物基质是通过下述方法制备的：提供一种金属离子前体，所述前体包括至少一种在载体材料中溶解或分散的抗微生物有效的金属离子源；将所述的前体沉积在基质的至少一个表面；在约20℃至约105℃的温度下从金属离子前体中除去挥发物干燥所述基质；在600-650℃的温度下加热所得的基质2-5分钟，把来自前体的抗微生物金属离子交换或注入到玻璃或类似玻璃的基质中。 A glass or glass-like substrate having a contact-killing, non-leaching antimicrobial effective amount of metal ions contained in at least one surface region thereof, and having a color of b* ≤ +6 on the CIE international color scale is disclosed. The antimicrobial substrate is prepared by providing a metal ion precursor comprising at least one source of antimicrobial effective metal ions dissolved or otherwise dispersed in a carrier material; depositing the precursor onto at least one surface of the substrate; drying the substrate at a temperature of from about 20 DEG C to about 105 DEG C by removing volatiles from the metal ion precursor; and heating the resulting substrate at a temperature of about 600 - 650 DEG C for 2 - 5 min. to exchange or otherwise implant antimicrobial metal ions from the precursor and into the glass or glass-like substrate.
