Nanodiamond-Assisted Dispersion of Carbon Nanotubes and Hybrid Nanocarbon-Based Composites
Nanodiamond particles were used to disperse carbon nanotubes (CNTs), allowing the formation of their stable colloidal suspensions. Both multiwalled carbon nanotubes and single walled carbon nanotubes could be suspended in deionized water using either detonation nanodiamonds or high pressure, high temperature nanodiamonds. Negatively charged nanodiamonds were found to suspend carbon nanotubes in deionized water more favorably as compared to positively charged particles, possibly caused by electrostatic interactions. Robust, all-carbon films made from nanodiamond-nanotubes mixtures were prepared with multiwalled nanotubes and were found to be most stable for high pressure high temperature nanodiamonds and least stable for positively charged detonation nanodiamonds. Finally, chemical conjugation of nanodiamonds with carbon nanotubes is considered for advanced applications.
