Description
Summary:The dispersion effect of five cyclodextrins (CDs) on carbon nanotubes (CNTs) was studied. 2-HB-β-CD is the most efficient dispersing agent. The dispersing ability of CDs on the dispersion of CNTs was 2-HB-β-CD >> 6-HP-β-CD > β-CD > 6-HB-β-CD > 2-HP-β-CD. The movement in the FTIR spectra of the asymmetric and symmetric stretching vibrations of O-H of the composites means hydrogen bonding was an important factor on the dispersing ability. These results indicate that the type of interaction might be a combination of a weak interaction similar to a van der Waals type and hydrogen bonding mechanism.
