Paper Title:
Preparation of Modified Cu-Antibacterial White Carbon Black by Microwave Drying
  Abstract

This paper investigated the synthesis and characterization of the Cu-antibacterial White Carbon Black modified by electrolyte, surfactant, and organic solvent. The sol-gel method was used to prepare the White Carbon Black carrier. Cu2+ was selected to be the antibacterial ion, and sodium nitrite (electrolyte), sodium dodecylbenzene sulfonate (surfactant), ethanol (organic solvent) was selected to be the modifiers. They were synthesized on the White Carbon Black carrier. These as-synthesized modified antibacterial materials were characterized by inductively coupled plasma, particle size measurement instrument and enumeration tests (Escherichia coli as experimental bacterium). The result showed that the amount of antibacterial ions and bacteriostasis rate of modified Cu-antibacterial White Carbon Black are higher than those of the common Cu-antibacterial White Carbon Black. In addition, the particle sizes of modified samples can be extended down to 7 µm with a narrow size distribution. Other advantages of modified Cu-antibacterial White Carbon Black are short drying time (only 5 min by microwave), good thermal and light stability.
