Abstract

In this paper, the dispersion stability of multi-walled carbon nanotubes in combination with different metal particles was investigated. The available time of dispersions of metal-coated carbon nanotubes prepared by water bath ultrasonic dispersion was obtained. The UV-vis spectrophotometer was then adopted to measure the absorbance of the prepared carbon nanotubes dispersions. Under conditions of temperature control and no temperature control, the influences of different types of surfactants (SDBS, oleic acid, and polymers) on the stability of metal-coated carbon nanotubes dispersions were studied and compared with the results of untreated multi-walled carbon nanotubes. The results demonstrated enhanced stability of carbon nanotubes dispersions prepared by a custom temperature control system. The order of dispersants effects is polymers > SDBS > oleic acid, and the dispersion stability decreased in an order of untreated carbon nanotubes > iron-coated carbon nanotubes > nickel-coated carbon nanotubes. The metal coating increased the density of carbon nanotubes, thereby easily inducing settlement and reducing the dispersion suspension stability.
