摘　　要：通过在过氧化氢化学氧化法和 K Mn O4 -H2 O2 氧化法制备硫酸石墨插层化合物的基础上 ,详细讨论了其物理性质 ,如物相分析、热分析、红外谱图分析、导电性和低温比热的性质等。其中 XRD研究表明石墨的表面氧化对插层反应是必不可少的。TG和 DTA分析表明过氧化氢氧化法制备产物插层反应完全。IR谱进一步确证热分析的结果。低温比热研究表明在某些温区发生相变 ,十分“类似于”纳米材料的低温比热行为。The graphite hydrogen sulfate intercalation compound was prepared with H 2O 2 chemical oxidation preparation method and KMnO 4 H 2O 2 oxidation methods, and the physical properties of graphite hydrogen sulfate intercalation compounds are investigated in detail through XRD analysis, thermal analysis, and the analyses in respect of IR spectra, conductivity and low temperature specific heat. XRD analysis shows that the graphite surface oxidation is indispensable to intercalation reaction. TG and DTA analyses show that the sample of H 2O 2 chemical oxidation is excellent. IR spectra confirm the result of thermal analysis. The determination of low temperature specific heat suggests that guests of intercalation compound are in the state of “cluster” or “nano particle”.
