石墨结构层包嵌铜纳米薄片是一种纳米尺度的复合材料,结构为铜纳米片被机械包嵌在石墨碳网之间.在其Raman光谱中,E2g2模的振动频率出现了红移,表明铜纳米薄片外部原子将部分电荷转移给了碳网,这与X射线光电子能谱分析结果一致.由1阶和3阶石墨层间化合物前驱体还原的样品,其Raman光谱具有弯曲碳网的特征,这可能来自薄片边缘的卷曲.前驱体的Raman光谱与其他受主型石墨层间化合物的Raman光谱一致.
Graphite layer embedded copper nanosheets are nanoscale composites with a structure in which copper nanosheets are mechanically encapsulated between graphite carbon networks and show a red shift in the Raman spectrum of the vibrational frequency of the E2g2 mode, The external charge of copper nanoflakes transferred some of the charge to the carbon network, which is consistent with the X-ray photoelectron spectroscopy analysis.The Raman spectra of the samples reduced by first- and third-order graphite intercalation compound precursors have the characteristics of a curved carbon network , Which may come from the curling of the edge of the sheet.The Raman spectrum of the precursor is consistent with the Raman spectra of the other acceptor-type graphite intercalation compounds.
