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

doi:10.3969/j.issn.0251-0790.2012.06.016

Abstract

Abstract: Two β-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, DMSO and ethylene glycol better, which is similar to GO. At the same time, introduction of CDs improves significan-tly the thermal stability of nanomaterials, which suggest their great potential as the flame retardants industry.

Key words: Cyclodextrin, Functionalized graphene, Thermal stability
