摘　　要：合成了具备优异导电性能的氧化石墨/碳纳米管层状杂化材料。通过红外、拉曼光谱和X射线衍射,证明了氧化石墨片层间的氢键作用随着碳管在杂化产物中的增加而减弱,同时氧化石墨的层间距变大;采用扫描电镜观察了杂化材料的横截面和表面形貌,氧化石墨原先堆积状的片层结构由于碳纳米管的插入产生了剥离,碳纳米管也得到良好的分散;当氧化石墨与碳纳米管的质量比由1∶1变为1∶4时,电导率提高了5个数量级。Symhesized graphite oxide（GO）/multi-wall carbon nanotubes（MWNTs） hybrid malcrial wilh good conductive performance. The hydrogen bonding between GO layers in the hybrid material was subsided when the conlenl of MWNTs was increased, anti interlayer spacing of GO was enlarged proved by IR.Raman spectra and X-ray diffraction. The intersecting surface and surface images of hybrid material were observed by SEM, it showed thal the original heaped CGO layer-slructure happened to exfoliate when MWNTs inserled, and MWNTs had a good dispersion in hybrid material. When the ration of GO and MWNTs charged 1 ： ,1 from 1 ： 1. the conductivily increased hy 5 orders of magnitude.
