Abstract
To develop an antibacterial tempered glass for applications to various building facilities and household products, the antibacterial activity of domestic materials was investigated, and a tempered glass sample was produced with silver, copper, and zinc, having an antibacterial activity of 99% or more at a specific concentration. The measured antibacterial activity of the samples, in which silver, copper, and zinc were dispersed in ethylene glycol + glycerol, was more than 99%. Measurements of the thickness of the coated metal material by washing using a surface analyzer showed that the thickness decreased by less than 1% in various types of detergents, including water, but only approximately 10% in the alkaline detergents. To check the human safety of the samples, a cytotoxicity test was performed through an MTT assay; the samples showed no cytotoxicity. Finally, a Live/Dead kit or film adhesion method showed that the antibacterial activity of the prototype was more than 99%. Therefore, the high-functional antibacterial effect of tempered glass was developed using domestic materials and may be used in various products in the future.
