石墨烯的新方法剥离制备及表征

AbstractGraphene was prepared by traditional method and organic carbon by addingmedium strength sulfuric acid (12 mol/L)as intercalation agent.Natural graphite wasstripped in alkaline solution.the prepared graphene structure was characterized by Xray diffraction (XRD),infrared (FTIR),ultraviolet (uv)and fourier transform raman(Raman)spectroscopy.finally,the results show that graphite is exfoliated by organiccarbon intercalation,and the infrared spectrum shows the wavenumber ofoxygen-containing functional groups such as-OH,COOH,C-O-C,which indicatesthat graphene has a certain oxidation effect.the uv spectra showed that the maximumabsorption peak of the prepared product was red-shifted by adjusting the reductionmode of the PH.finally,the XRD and Raman methods were used to analyze,and theresults showed that the organic carbon auxiliaries were auxiliary to enhance theintercalation and stripping effect of graphene.Keywords:Organic carbon;Auxiliary intercalation;Graphene
