Pseudopolyrotaxane Structure Constructed by Polycaprolactone (PCL) Grafted on Multi-Walled Carbon Nanotubes and α-Cyclodextrins

Article Preview

Abstract:

Abstract The multi-walled carbon nanotubes (MWNTs) are modified through acidification, followed by the graft of polycaprolactone. The supramolecular forces of α-cyclodextrins (α-CDs) and PCL are used to produce MWNTs hybrid materials with pseudopolyrotaxane structure. XRD, FTIR, TGA, DSC are used for the characterization of its product. The preparation of this hybrid material provides a new approach for modifying carbon nanotubes in supramolecular chemistry with the expectation of applying this hybrid materials to the field of biomedicine.
