摘要 采用2种有机合成路线制备了结构不同的环糊精共价修饰的功能化石墨烯纳米材料,并利用FTIR,XRD,TEM,SEM和TG分析等技术对产物的结构和性能进行了表征.结果表明,2种石墨烯基纳米材料由于合成策略的不同导致溶剂分散性能存在一定的差别,但它们均可均匀分散于N,N-二甲基甲酰胺(DMF)、二甲基亚砜(DMSO)和乙二醇中.同时,环糊精的引入使其热学稳定性显著提高.该材料在阻燃型复合材料等领域中具有一定的潜在应用价值. 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 significantly the thermal stability of nanomaterials, which suggest their great potential as the flame retardants industry.
