Method of nanocarbon/montmorillonite powder extraction

In this reported work, carbon/montmorillonite (C/MMT) nanometre particles and micrometre particles blended were extracted by the froth flotation method, extraction and density gradient centrifugation. X-ray diffraction, scanning electron microscopy, transmission electron microscopy and particle size analysis were employed to characterise the C/MMT extracted before and after. The results have shown that the froth flotation method cannot effectively collect C/MMT nanocomposites, and the extraction is not effective, whereas density gradient centrifugation can collect vari-size grained C/MMT nanocomposite particles. On using density gradient centrifugation, the thicknesses of C/MMT nanocomposite particles are <;20 nm.
