Preparation of β-Cyclodextrin Functionalized Graphene and Enhancement of the Thermal Stability

Two beta-cyclodextrin modified graphene nanomaterials were prepared by employing two synthetic strategies. Their structures and performances were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction(XRD), transmission electron microscope(TEM), scanning electron microscopy (SEM) and thermogravimetric analysis(TGA). The results showed that their dispersion behaviors would be influenced by the structures of nanomaterials. GO-CDs and GO-TDI-CDs can be dispersible in DMF, HMSO and ethylene glycol better, which is similar to GO. At the same time, introduction of CDs improves significantly the thermal stability of nanomaterials, which suggest their great potential as the flame retardants industry.
