TI  - Mixed Surfactant Solutions for the Dispersion of Multiwalled Carbon Nanotubes and 
      the Study of Their Antibacterial Activity.
PG  - 2239-45
AB  - The dispersibility of mixed surfactant-modified multiwalled carbon nanotubes 
      (MWNTs) and their effect on antibacterial activity were examined. The ratio of 
      9:1 between sodium dodecyl benzene-sulfate (SDBS) and hexadecyltrimethylammonium 
      bromide (CTAB) showed the highest dispersing power for MWNTs. The use of mixed 
      surfactants enabled the MWNTs to form a stable dispersion at a lower total 
      surfactant concentration than their concentrations when used alone. UV-vis 
      spectroscopy, transmission electron microscopy (TEM) and Fourier transform 
      infrared spectroscopy (FT-IR) were used to characterize the dispersion of MWNTs 
      in the aqueous phase. The results indicated that the surfactant molecules had 
      been successfully adsorbed onto the surface of the MWNTs. The mixed 
      surfactant-modified MWNTs exhibited a strong antibacterial activity and 
      concentration dependence to Staphylococcus aureus (S. aureus). Based on the 
      considerations of the cost and environmental impact, the use of mixed surfactants 
      (SDBS-CTAB) should be more favorable for the stable dispersion of MWNTs and the 
      improvement of antibacterial activity than the use of a single surfactant.
