不同pH下GO-ATP纳米复合材料的分析与表征

摘要

GO-ATP nanocomposite were prepared via ultrasonic and magnetic stirring method.The effects of different preparation conditions of pH on the structure of GO-ATP nanocomposite were studied by X-ray diffraction analysis(XRD),fourier transform infrared spectroscopy(FTIR),scanning electron microscopy(SEM) and other tests analysis means.The results show that pH has obvious effect on the formation GO-ATP nanocomposite.Polar environment is not conducive to the formation of composite.When the pH is 4~10,the basal spacing of GO-ATP nanocomposite increases with the increase of pH,and the oxygen functional groups peak crescendo.When pH=10,layer spacing is the largest.SEM display that ATP intercalated in the GO layer,effectively inhibit the aggregation of GO.%通过超声波+磁力搅拌法,制备了GO-ATP纳米复合材料,采用X射线衍射(XRD)仪、傅里叶变换红外光谱(FTIR)仪、扫描电子显微镜(SEM)等手段,研究不同pH制备条件对GO-ATP纳米复合材料结构的影响.结果表明,pH值对GO-ATP纳米复合材料形成过程影响明显,极性环境不利于复合材料的形成;当pH为4~10时,随pH增大,GO-ATP纳米复合材料层间距增大,且含氧官能团峰渐强,当pH=10时,层间距最大,SEM显示ATP插层于GO片层中,有效抑制了GO的团聚.
