Carbon nanotubes with multi walled structure have been successfully prepared and commercialized by Endo's process based on Catalytic Chemical Vapor Deposition (CCVD) Method. These multiwalled carbon nanotubes have an extremely high thermal conductivity as high as 1000-2000W/mK at room temperature. In the present work, plastic composite with the tubes filler has been prepared as a precursor of carbon nanotubes/carbon composite.By controlling the precursor structure, the C/C composite has been obtained and the properties of C/C composite are very much depending upon the structure of presursor's. There have been lot of difficulties for preparing the precursor and carbonization as well as graphitization for C/C composite formation, and we can get the composite materials.The thermal conductivity of the C/C composite is strongly affected by the structure of precursor, and we got the value more than 500W/mK thermal conductivity at room temperature. Not only thermal conductivity, but also other valuable functions have been clarified, which are also promising for future applications.Present work have reviled the possibility of C/C composites of carbon nanotubes with high thermal conductivity as well as other functional properties, and for preparation of the materials the structural control of resin-based precursors is one of the most important process.

采用基于催化化学气相沉积（CCVD）的Endo工艺成功制备了多壁碳纳米管，并实现了商业化。这些多壁碳纳米管在室温下具有高达1000- 2000 W/mK的极高热导率。本工作制备了以管状填料为碳纳米管/碳复合材料前驱体的塑料复合材料，通过控制前驱体的结构，得到了C/C复合材料，而C/C复合材料的性能在很大程度上取决于前驱体的结构。C/C复合材料的制备经历了前驱体的制备、炭化和石墨化等诸多困难，最终得到了C/C复合材料，前驱体的结构对C/C复合材料的导热系数有很大的影响，室温下C/C复合材料的导热系数大于500 W/mK。碳纳米管不仅具有导热性能，还具有其它一些有价值的功能，具有广阔的应用前景。目前的工作揭示了碳纳米管C/C复合材料具有高导热性能和其它功能的可能性，而树脂基前驱体的结构控制是制备这种材料的重要环节。
