Preparation and Characterization of Cu-Inorganic Antibacterial Material Containing Rare Earths
In this study, we synthesized a new inorganic antibacterial material, of which Cu2+ was selected to be the antibacterial ion, cerous nitrate served as the additives, and the white carbon black was chosen as the carrier, which was prepared by a sol-gel method. The as-synthesized antibacterial material was characterized by inductively coupled plasma, particle size measurement instrument, scanning electron microscope and enumeration tests. The result showed that the amount of antibacterial ions and bacteriostasis rate of this new material are higher than those for the common Cu-inorganic antibacterial material without rare earths. In addition, the particle size of this material can be extended down to 20 μm with a narrow size distribution. Other advantages of this material are its loose and dispersive structure.
