Exfoliated graphite has very large sorption capacity for oils. Utilizing this property, various metal complexes, silicone compounds, metal alkoxides and others were impregnated into exfoliated graphite, and pretreated, mainly by heat treatment in air or hydrolysis in water vapor, to form precursors. By heating these precursors in an inert atmosphere, the following multi-functional carbonaceous materials were synthesized.(1) Ni/graphite composite, Fe/graphite composite, Fe_3O_4/graphite composite (potential applications : magnetic materials, absorber for electromagnetic radiation, catalyst, and so on)(2) Graphite coated with ultra thin Si-C-O composites (oxidation resistant carbon material, conductive materials at high temperatures)(3) Mn2O3 or MnO2/graphite composite (electrode materials for super capacitors)(4) Nano-particles of single or multi-component metal carbides, such as β-SiC, TiC, ZrC, (Ti,Zr)C and others.The developed method to synthesize (4) is promising as an industrial process because it is simple and low cost.

膨胀石墨对油具有非常大的吸附能力。利用这种性质，将各种金属络合物、有机硅化合物、金属醇盐等浸渍到膨胀石墨中，并主要通过在空气中热处理或在水蒸气中水解来预处理以形成前体。通过在惰性气氛中加热这些前体，合成了以下多官能碳质材料。(1)Ni/石墨复合材料，Fe/石墨复合材料，Fe_3O_4/石墨复合材料（潜在应用：磁性材料、电磁辐射吸收剂、催化剂等）（2）超薄Si-C-O复合材料包覆石墨（抗氧化碳材料，（3）Mn 2 O3或MnO 2/石墨复合材料（4）单组分或多组分金属碳化物的纳米颗粒，如β-SiC、TiC、ZrC、（Ti，Zr）C等。
