Study on properties of the compound inorganic antibacterial agent ions of copper and zinc

The composite inorganic antibacterial materials were prepared by sol-gel method in this paper,in which Al_2O_3 as support carrying Cu~2+,Zn~2+.The factors which affected the antibacterial property were studied,including the preparing condition and the particle size.As the ratio of Cu~2+,Zn~2+ is(0.8～1.18)∶2,the sintering temperature is 800 and 900℃,and holding 2h at the temperatures,the antibacterial property is the best;the average particle size is 81.7nm and the antibacterial effective substance in the sample are the oxide of Cu~2+,Zn~2+ and the solid solution structure that created by Cu~2+,Zn~2+ with Al~3+ or Al~3+ and O~2-.
