| Abstract: | After being purified with the mixture of sulfuric acid and nitric acid,the carbon nanotubes (CNTs) prepared by CVD were dispersed in aqueous solution with various surfactants by ultrasonic agitation. Then the dispersity was evaluated with settlement time and the spectral absorption properties.It's found that the carbon nanotubes were dispersed very well in the HTAB or OP emulsifying agent with an appropriate concentration. |
